Question

After a major fire, grasses that are pioneer species start to grow in the ashy soil. The following list includes some of the ways that the grasses affect the ecosystem.
absorbing nutrients from the soil
absorbing water from the soil
providing food for animals
preventing erosion
Which of the items on the list contribute to ecological succession in the burned area?

Answer 1

Answer:

Providing food for animals

Answer 2

Answer:

preventing erosion and providing food for animals

Explanation:

Ecological succession is a process that starts with hardy pioneer species and leads to a diverse ecosystem. After a fire, the ashy soil is vulnerable to erosion by wind and water. Grasses prevent erosion so that the nutrients in the soil are still available for other plant species. By providing a source of food, grasses attract animals to the area.
