Answer 2

Nutrients are limited

Step-by-step explanation:

If nutrients are abundant, consumers do not need to compete with one another for resources. In contrast, if there is not much food around, then consumers have to compete with one another to make sure they get adequate nutrition. For example, imagine the consumers are rabbits and there are not very many plants for them to eat. These rabbits will be in competition with one another. In contrast, if there are lots of plants to eat, they will not need to compete for resources.

Consumers do not make their own nutrients, producers, such as green plants, create their own nutrients by photosynthesis.
