why is the number of producers usually much greater than the number of other organisms in an ecosystem?\na. producers have access to more nutrients than other organisms do.\nb. competition for resources is greater for other organisms than for producers.\nc. producers need to provide enough energy to satisfy the needs of other organisms.\nd. available energy decreases as it is transferred from producers to other organisms.
Answer
Brief Explanations:
In an ecosystem, energy transfer follows the 10 - percent rule. As energy moves from producers to consumers, a large amount is lost at each trophic level. Producers need to be numerous to capture enough energy from the sun and provide sufficient energy to support higher - trophic levels.
Answer:
D. Available energy decreases as it is transferred from producers to other organisms.
