Soil Ecosystems Review

Identify the following relationship and explain why The cattle egret eats insects that have been disturbed when the cattle forage. A hermit crab taking up residence in an empty seashell. Fleas and mosquitoes feed on blood from other organisms Aphids eat sap from plants. In the ocean, certain species, like shrimps and gobies, will clean fish. They remove parasites, dead tissue, and mucous.
