b. chemical changes and flow of water
c. physical changes and flow of energy
d. physical changes and flow of water

Answers

Answer 1
Answer:

Answer:

a. chemical changes and flow of energy

Explanation:

Energy flow from one organisms of one tropic level to other, matter cycling and transformation of energy are the functions that sustain the ecosystem. Transformation of solar energy into chemical energy by plants serves as energy source for all heterotrophic living beings in the system. The heterotrophic organisms digest the ingested food (chemical change) to release energy to support their life processes. The energy stored at one tropic level is carried to next tropic level via food chain and food webs and represents the interaction between living components of ecosystem.

Answer 2
Answer: it is      A  both chemical changes and flow of energy

Birds migrate from their original habitat to new habitats to search for food and better climate. How is bird migration a kind of gene flow?

Answers

Gene Flow is an exchange of genes between two different populations. If birds migrate from their original habitat into another habitat that is inhabited by another population, they might breed and exchange genes. 

For example, a population of short birds migrates into the habitat of a population of tall birds. This might result in the hatching of medium height birds. 

Answer: During migration, birds may carry seeds or pollen from fruits and flowers in their other habitat. They deposit these seeds and pollen grains in their new habitat. If the seeds take to the new conditions, the new kinds of plants expand the area's gene pool.

Which of the following is an example of mutualism? (1 point)A)Bacteria live in root nodules of a plant, processing nitrogen into ammonia for the plant and receiving protection and a steady food supply in return.(My answer)
B)Moss benefits from exposure to light and moisture as it grows on a tree trunk that is not affected by its presence.
C)Fleas live in the fur of a dog where they periodically pierce the dog’s skin and feed on its blood.
D)Cowbirds lay their eggs in the nests of other birds that are often tricked into rearing the cowbird chicks instead of their biological chicks.

Answers

The correct answer is A. Bacteria live in root nodules of a plant, process nitrogen to ammonia for the plant, receive protection and steady food supply which is being got in return.

Mutualism is referred to as the way two organisms which are of different species exist in relationship whereby every individual benefits from activity of each other.

The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism.

Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.
