Answer:Each and every one of us have several roles. Organisms in a community play other roles too. An organism's role within an ecosystem depends on how it earn its nutrients. Organisms collect their nutrients in very different actions, so they have different roles in an ecosystem.
Explanation:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Answer:
A) photorespiration.
Explanation:
Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.
The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate.
The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.
The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.
Thus, Option-A is correct.
The difference between respiration and breathing is their functions. Breathing is when your body uses your lungs to inhale and exhale oxygen. Respiration is a chemical reaction where your body uses oxygen to eliminate or break apart Glucose so it could give you energy.
Hopefully this helps :)
