Question

1. which of the following is an example of mutualism? a) a hookworm feeding on a dogs intestine b) a shark eating a smaller fish c) a bird eating ticks off a zebra d) a clownfish hiding in a sea anemone 2. true or false _ producers make their own food using sunlight. _ omnivores eat only plants. _ in parasitism, both organisms benefit. 3. short answer why are decomposers important in an ecosystem?

Explanation:

1. Mutualism is a symbiotic relationship where both organisms benefit. A bird eating ticks off a zebra is mutualism as the bird gets food and the zebra gets rid of parasites. A hookworm - dog relationship is parasitism, shark - fish is predation, and clownfish - sea anemone is commensalism.
2. Producers like plants use sunlight for photosynthesis to make food (True). Omnivores eat both plants and animals, not only plants (False). In parasitism, one organism benefits and the other is harmed (False).
3. Decomposers break down dead organisms and waste, recycling nutrients back into the ecosystem, which are then used by producers for growth.

Answer:

1. C. A bird eating ticks off a zebra

2.

• Producers make their own food using sunlight: True
• Omnivores eat only plants: False
• In parasitism, both organisms benefit: False

1. Decomposers break down dead organisms and waste, recycling nutrients back into the ecosystem for producers to use.
