How does algae respond to its environment?
Algae have a variety of adaptations that help them survive including body structures defense mechanisms as well as reproductive strategies. Some algae have holdfasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae such as Sargassum have gas-filled structures called floats.
Why do animals and plants exchange energy and materials differently?
Explanation: Most if not all plants are producers and they make their own food using sunlight and raw materials through a process called “photosynthesis”. … Plants get their energy in form of starch whereas animals get it in form of glycogen.
Why is energy important in the ecosystem?
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. … At each stage of a food chain most of the chemical energy is converted to other forms such as heat and does not remain within the ecosystem.
How does the energy captured and transferred among organisms?
