Where did the crops we enjoy today originate from?
The crops we enjoy today originated from few areas having high biodiversity. Biodiversity is nothing but the variety or variation of life on earth. Without variety a single type of crop can be lost during natural calamities such as famine.

What is a hybrid crop *?
A hybrid plant is the result of cross pollinating two different plant varieties and growing the seed the mix produces. The plant that grows from that seed combination is called a hybrid. Commercial cross planting is done to get some type of valued attribute of each initial variety into the offspring.

How is biotechnology used in agriculture?
How is Agricultural Biotechnology being used? Biotechnology provides farmers with tools that can make production cheaper and more manageable. For example some biotechnology crops can be engineered to tolerate specific herbicides which make weed control simpler and more efficient.
How is biotechnology different from the traditional way of improving crops?
The difference is that traditional forms of breeding change the plant’s genetics indirectly by selecting plants with specific traits while genetic engineering changes the traits by making changes directly to the DNA.
How does biotechnology increase crop yield?
Biotechnology allows farmers to grow more food on less land using farming practices that are environmentally sustainable. Through biotechnology: Seeds yield more per acre plants naturally resist specific insect pests and diseases and farming techniques improve soil conservation.
How can we protect the coral reefs?
- Recycle and dispose of trash properly. Marine debris can be harmful to coral reefs. …
- Minimize use of fertilizers. …
- Use environmentally-friendly modes of transportation. …
- Reduce stormwater runoff. …
- Save energy at home and at work. …
- Be conscious when buying aquarium fish. …
- Spread the word!
Are coral reefs alive?
What do coral fish eat?
algae
Herbivores feed on plants. The four largest groups of coral reef fishes that feed on plants are the parrotfishes damselfishes rabbitfishes and surgeonfishes. All feed primarily on microscopic and macroscopic algae growing on or near coral reefs.
What are the benefits of hybrid plants?
Hybrid plants are usually more vigorous and faster growing than other plants. This can be great for those working in agriculture as they can reap greater crops and make more money. These plant types are also more resistant to many diseases and afflictions which effect parent plants.
Why are hybrid crops important?
Hybrid seeds have some advantages: they are easier and faster to grow they adapt better to stress and they produce plants with larger fruit higher yields disease resistance and longer shelf life than heirlooms.
Why are hybrid crops good?
In general hybrids offer some combination of these favorable traits: dependability less required care early maturity higher yield improved flavor specific plant size and/or better disease resistance. Hybrid vegetables typically look like the veggies you’d find at a supermarket.
How hybrid crops are produced and discuss their economic importance?
In agriculture and gardening hybrid seed is produced by cross-pollinated plants. … Hybrids are chosen to improve the characteristics of the resulting plants such as better yield greater uniformity improved color disease resistance. An important factor is the heterosis or combining ability of the parent plants.
Do hybrid plants produce seeds?
Are hybrid plants stronger?
One of the first things the plant scientists noticed when they began crossing different pure lines was that hybrid plants were usually more vigorous than their parents. The simple act of crossing different strains resulted in higher yields and stronger plants. They had discovered “hybrid vigor.”
Are humans endangered?
GENEVA – Nearly a quarter of all deaths worldwide are linked to environmental issues. That’s 12.6 million deaths every year according to WHO. “Human beings really are the most important endangered species ” said Margaret Chan WHO’s outgoing Director-General.
How do we declare species threatened or endangered?
A species is added to the list when it is determined to be an endangered or threatened species because of any of the following factors: ∎ the present or threatened destruction modification or curtailment of its habitat or range ∎ overutilization for commercial recreational scientific or educational purposes ∎ …
Who determines endangered?
The List of Endangered and Threatened Wildlife (50 CFR 17.11) and the List of Endangered and Threatened Plants (50 CFR 17.12) contain the names of all species that have been determined by the U.S. Fish and Wildlife Service (Service) or the National Marine Fisheries Service (for most marine life) to be in the greatest …
How can efforts to preserve endangered species lead to conflicts?
Efforts to preserve endangered species can lead to conflicts such as money or possibly unintentional harm to the species. Lead poisoning and pesticides contributed to their decline ?
Which best protects animal species that are endangered?
Tell this administration to protect the future of wildlife and maintain the full extent of the ESA. The US Endangered Species Act (ESA) is our nation’s most effective law to protect at-risk species from extinction with a stellar success rate: 99% of species listed on it have avoided extinction.
What are the advantages of protecting an entire ecosystem versus a single species?
The advantage of protecting entire ecosystems is the most effective way to save species because species confined to a small area could be wiped out by a single natural disaster. Some species require a large range to find adequate food or mate.
What are some ways to protect species from extinction?

How do nature preserves help protect biodiversity?
How do nature preserves help protect biodiversity? They preserve habitats and prevent extinctions of many species. Why is it usually better to preserve on large area of land instead of a few smaller areas of land? Larger areas have more species than smaller areas.
How is biotechnology useful in developing food crops and in the agriculture process?
Biotechnology is being used to address problems in all areas of agricultural production and processing. This includes plant breeding to raise and stabilize yields to improve resistance to pests diseases and abiotic stresses such as drought and cold and to enhance the nutritional content of foods.
