Question

ationships between organisms are described below. what type of relationship does each statement describe?

predation commensalism mutualism competition

description relationship
algae grows on spider crab shells and helps to camouflage the crab.
bass are large fish that hunt smaller fish, such as herring.
clams and shrimp both live in ponds and streams and filter small animals and plants from the water.
fish often hide in a grass called the swamp couch, which grows in shallow waters in marshes.

Explanation:

• Algae and spider crab: Algae benefits by having a place to grow, and the crab benefits from camouflage. This is a mutual benefit, so it's mutualism.
• Bass and smaller fish: One organism (bass) hunts and eats another (smaller fish), which is the definition of predation.
• Clams and shrimp: They live in the same area and compete for the same food (small animals and plants filtered from water), so it's competition.
• Fish and swamp couch: The fish benefits from hiding (protection), and there's no indication that the swamp couch is affected (either positively or negatively). This is commensalism.

Answer:

• Algae grows on spider crab shells and helps to camouflage the crab: mutualism
• Bass are large fish that hunt smaller fish, such as herring: predation
• Clams and shrimp both live in ponds and streams and filter small animals and plants from the water: competition
• Fish often hide in a grass called the swamp couch, which grows in shallow waters in marshes: commensalism
