What Happens To Productivity As Rainfall Increases

What Happens To Productivity As Rainfall Increases?

What happens to productivity as rainfall increases? As rainfall increases the rate of plant tissue production slowly decreases. … Since plants need sunlight in order to photosynthesize the amount they receive would definitely affect their productivity.

What factors other than rainfall might affect primary productivity?

Net Primary Productivity (NPP) is the total amount of energy converted from solar energy to chemical energy with the subtraction of the energy used for respiration. Net Primary Productivity is affected by temperature water availability carbon dioxide and nutrients all of which are abiotic factors.

Which of the following is a possible source of energy for Earth’s living things I Wind energy II Solar Energy III chemical energy?

Therefore sunlight and chemical energy are the sources of energy for living things.

Food web

The series of steps in which a large fish eats a small fish that has eaten algae is: Food web.

Which process describes nitrogen fixation?

The nitrogen cycle moves nitrogen through the abiotic and biotic parts of ecosystems. … The nitrogen gas must be changed to a form called nitrates which plants can absorb through their roots. The process of changing nitrogen gas to nitrates is called nitrogen fixation. It is carried out by nitrogen-fixing bacteria.

What factors increase primary productivity?

A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water nutrients and climate) are favourable. The presence of some forms of secondary energy can also help to increase the primary productivity rate.

What are 3 factors that might affect the primary productivity of a body of water?

Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input temperature and moisture levels carbon dioxide levels nutrient availability and community interactions (e.g. grazing by herbivores) 2.

What is the largest source of energy for the Earth Class 9?

Solar Power. The Sun is Earth’s main source of energy making the development of solar power a natural choice for an alternative energy source.

What is the largest source of energy for the Earth Brainly?

Answer: The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun and sunlight can also be used to produce electricity from solar (photovoltaic) cells.

Why does life on Earth depend so heavily on sunlight?

Life on Earth depends on the sun because consumers depend on producers for sustenance. Producers need the sun’s energy to get food through the process of photosynthesis. So without the sun producers would perish which in turn would cause the consumers to starve to death.

What is the original source of energy that flows through most ecosystems?

the sun

The primary source of energy for almost every ecosystem on Earth is the sun.

Which type of pyramid shows the amount of living tissue?

Biomass Pyramid

Biomass Pyramid: Represents the amount of living organic matter at each trophic level. Typically the greatest biomass is at the base of the pyramid.

Which group of organisms is always found at the base of a food chain or food web?

As you probably know the organisms at the base of the food chain are photosynthetic plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers and they get their energy directly from sunlight and inorganic nutrients.

What combines nitrogen and oxygen in the air?

Atmospheric Fixation

The enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These dissolve in rain forming nitrates that are carried to the earth.

Why is Ammonification important in the nitrogen cycle?

In crop and livestock production systems nitrogen assimilated by plants and animals is converted into cellular tissue. … Ammonification of organic nitrogen is an important processes in water because biological assimilation of ammonium by bacteria biofilms and aquatic plants is preferred to nitrate assimilation.

What is Ammonification also known as?

Ammonification is the last step of the nitrogen cycle involving an organic compound and is the intermediary step between the depolymerization of large organic molecules and the nitrification step (Fig. … In marine ecology ammonification is also referred to as ammonium regeneration and ammonium recycling.

Where is ocean productivity highest?

Higher chlorophyll concentrations and in general higher productivity are observed on the equator along the coasts (especially eastern margins) and in the high latitude ocean (Figure 4a and b).

How does productivity increase in aquatic ecosystems?

On land it is driven by temperature and availability of water and nutrients modified by land use. In aquatic ecosystems primary productivity is driven by the availability of nutrients and light and to a lesser extent by temperature and other factors.

How does water limit primary productivity?

Lack of water is the main limit on primary production on the Earth’s surface. It has been found that in any area where there is an adequate water supply there will be a large amount of primary production. Water is primarily supplied through rain and the Earth’s weather system.

What factors affect productivity in the ocean?

Ocean Productivity. Abiotic factors like solar radiation and nutrients and biotic factors like zooplankton predation may affect ocean primary productivity. Productivity varies with the season and also locally and globally.

What affects primary productivity in the ocean?

Reduction of sunlight by sea ice is a major limiting factor for primary productivity in the Arctic Ocean. … In the Arctic Ocean photosynthetic algae can be adapted to rather low light conditions. It is possible for photosynthesis to be inhibited if these algae are exposed to too much light.

What are some of the factors that influence the primary productivity of the ocean?

  • Light: The light field varies with depth in the ocean with time of day and with time of year. …
  • Temperature: Temperature controls the enzyme-mediated dark-reaction rates of photosynthesis.
  • Species composition also influence rates of primary production.

What is the main source of energy of the sun?

The sun generates energy from a process called nuclear fusion. During nuclear fusion the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process radiant energy is released.

What is the main source for the formation of wind?

4. What is the main source for the formation of wind? Explanation: Wind is free and renewable form of energy which throughout history has been used to grind grain power ships and pump water. Wind is created when the sun unevenly heat the earth surface.

What is the largest source of energy for the Earth BYJU’s?

The Sun is the main source of energy on Earth.

What is the largest source of energy for the world?

Oil is the world’s largest energy source today. It is the dominant source of energy for the transport sector in particular.

  • Sunlight improves your sleep quality.

Why sun is called the ultimate source of energy?

Answer: Sun is the ultimate source of the because it provides energy in the form of light that helps the plants to make food and it is almost all the energies of the world that humans are also using .

What is responsible for 85% of the energy from the sun?

Since the Sun is a huge plasma ball made up primarily of hydrogen it is the fusion of hydrogen into helium that is responsible for 85% of the Sun’s energy output. The fusion of hydrogen to form helium is a proton–proton chain reaction.

What is the name of an organism that Cannot make its own food?

A heterotroph (/ˈhɛtərəˌtroʊf -ˌtrɒf/ from Ancient Greek ἕτερος héteros “other” and τροφή trophḗ “nutrition”) is an organism that cannot produce its own food instead taking nutrition from other sources of organic carbon mainly plant or animal matter.

What will happen if the producer in the food chain dies?

4. The removal of the producers would cause the collapse of the entire food web. Primary consumers or herbivores which feed on producers directly would die off. … Higher level consumers would suffer as organisms from lower trophic levels start to die off.

What will happen if all the primary consumer dies?

Primary consumers or herbivores which feed on producers directly would die off. The next to be affected would be the secondary consumers or carnivores that eat the primary consumers. … However even these dead organisms would run out and the entire food web would collapse.
