Question

How is a loss of biodiversity most likely to affect an ecosystem?

Answer 1

All the plants and animals in a ecosystem relay on each other to survive so loss of 1 species would mean numbers of others would fall and some may rise too muck

Answer 2

Loss of biodiversity affects the ecosystem in many ways. For example, if a species disappears, the animals/plants that it fed on will suddenly increase in population due to loss of predators. The predators of the lost species, however, will go down in population because its main source of food has disappeared.
