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.
Region of the World Percentage Value in Metric tons
North America 17 23,332,500
Asia 52 71,370,000
Africa 3 4,117,500
Europe 18 24,705,000
Latin America and the Caribbean 8 10,980,000
Oceania <u> 2</u> <u> 2,745,000</u>
100 137,250,000
We multiply the 137.25 million metric tons by its percentage to get its equivalent value in metric tons.
Asia uses 71.37 million metric tons.
In making the bar graph, The vertical line will be the percentage and the horizontal line will be the region. Bars of each region should have different colors for easy identification. Spaces between bars should be present, so that the bar graph will not be confused with the histogram.
Nitrogen Fixation. Good luck :)
Sperm production is hormonally driven. Brain hormones govern sperm production and are precisely controlled. So I say yes
