Question

1. write about it describe how human actions can affect ecological pyramids.

Explanation:

Considered human activities like deforestation, over - fishing and pollution and their effects on different trophic levels in ecological pyramids.

Answer:

Human actions can have various impacts on ecological pyramids. Deforestation reduces the number of producers at the base of the pyramid, decreasing available energy for higher - trophic levels. Over - fishing can deplete fish populations (secondary or tertiary consumers), disrupting predator - prey relationships and energy flow. Pollution can harm organisms at all levels, potentially causing population declines and altering the shape and balance of the ecological pyramid.
