Question

How do animals contribute to nutrient cycling in ecosystems?

Answer 1

Animals contribute to nutrient cycling in ecosystems in various ways. Some key contributions include:

1. Decomposition: Animals play a crucial role in breaking down organic matter through feeding and excretion, releasing nutrients back into the soil.

2. Fertilization: Animal waste, such as feces, contains valuable nutrients like nitrogen and phosphorus that enrich the soil and promote plant growth.

3. Seed dispersal: Animals aid in the dispersal of seeds, helping plant populations grow in new areas and contributing to biodiversity.

4. Grazing and predation: By consuming vegetation and other animals, animals regulate plant populations and control prey populations, which can impact nutrient availability in the ecosystem.

Overall, animals are integral to nutrient cycling processes in ecosystems, promoting the recycling and redistribution of essential nutrients for the functioning of the entire ecosystem.

Answer 2

Animals contribute to nutrient cycling in ecosystems in various ways. They play a crucial role in transferring nutrients between different trophic levels through consumption and decomposition. Animals help in breaking down organic matter, releasing nutrients back into the soil through their waste products. Additionally, some animals are involved in pollination and seed dispersal, which also contributes to nutrient cycling in ecosystems. Overall, animals play a vital role in maintaining the balance of nutrients in ecosystems.
