In every ecosystem, there are different organisms that interact with each other in a particular environment.
The components of an ecosystem interact and interrelate with the ones that form part of another. Every ecosystem is related to another one.
For example, in a food chain, a bird eats a fish, both animals belong to different ecosystems, but they are connected with each other.
Answer:
<em>The correct option is B) It is expected to decline in population size over time.</em>
Explanation:
A pyramid shape of a population will show that the population was the most abundant in the beginning. With the passage of time, as the age started to increase, the population started to decrease. Hence, the population is expected to decline in population size over time.
Other options, like option D, is not correct because, in a zero-growth population, the number of the birth rate will be equal to the number of death rates. Hence, a pyramid structure cannot represent such an illustration.
