Answer:
An ecosystem is biotic, not abiotic.
Explanation:
First, an ecosystem is a biological community of interacting organisms and their physical environment. Second biotic factors are nonliving things whereas biotic factors are living things in an ecosystem you have your producers or plants which then will be consumed by the primary consumers. With the primary consumers feeding the next group of consumers and then the next and then after they die they fertilize the ground allowing the producers to grow as it completes the circle of life.
Answer:
A. Evolution
Explanation:
Natural processes like speciation create variation in species, making them have biodiversity and a diverse gene pool.
Gradualism also allows for species to change gradually over time.
Both of these processes allow for evolution to occur, as speciation can create more favorable traits that will be passed down with the process of gradualism.
So, the correct answer is A, evolution.
The answer is a because they decompose the dead matter and recover the nutrients thereby providing nutrients for plants
Photosynthesis is a natural process by which trees and plants use energy from the sun and carbon dioxide from the air to make the food they need to live and grow. At the same time, the leaves or needles absorb carbon dioxide from the air. These raw materials flow to plant cells containing chlorophyll.
