Question

1. explain 2 things that could happen if the carp population increases.

Explanation:

In an ecosystem, an increase in carp population can have multiple impacts. Carp are often bottom - feeders. Firstly, they can stir up sediment while feeding. This can increase water turbidity, reducing light penetration and affecting photosynthetic organisms like aquatic plants. Secondly, they may compete with native fish species for food resources such as zooplankton and benthic invertebrates, potentially leading to a decline in native fish populations.

Answer:

1. Increased water turbidity due to sediment - stirring while feeding.
2. Competition with native fish for food resources, leading to potential decline in native fish populations.
