Question

making connections: directions: answer the questions in the yellow column on the right. notice some questions have multiple parts. use sentences to answer each part. be sure to elaborate fully on your answer and make connections to food webs and the le question your answer goes here in complete sentence 5. choose one species on the food web and explain how it would affect other species if it were removed from the ecosystem. 6. identify one omnivore on the food web. 6a. explain why this animal is an omnivore and use the food web to identify what it consumes. 7. identify two relationships within a community where at least one species is harmed. (please include the relationship name.) 8. identify two relationships within a community where at least one species benefits and no species are harmed. (please include the relationship name.)

Explanation:

1. Rabbits are herbivores. If removed, predators like foxes and wolves that rely on them for food would face reduced food - source, leading to potential decline in their populations. Also, plants that rabbits consume would have less grazing pressure and may over - grow.
2. A bear could be an example of an omnivore. It is an omnivore because it consumes both plants (berries, nuts) and animals (fish, small mammals) as shown in a typical food web.

6a. As mentioned above, a bear eats a variety of plant and animal matter. In the food web, it can be seen consuming berries from plants and catching fish from the water.

1. Predation (e.g., a lion preying on a zebra, where the zebra is harmed) and parasitism (e.g., ticks living on a dog, harming the dog).
2. Mutualism (e.g., bees and flowers, where bees get nectar and flowers get pollinated) and commensalism (e.g., barnacles on whales, where barnacles benefit by getting a place to live and whales are not harmed).

Answer:

1. If rabbits were removed from the ecosystem, predators that feed on them would have less food and plant species they consume would have less grazing pressure.
2. A bear.

6a. A bear is an omnivore as it eats both plants (berries, nuts) and animals (fish, small mammals) as indicated in the food web.

1. Predation (lion - zebra), Parasitism (tick - dog).
2. Mutualism (bee - flower), Commensalism (barnacle - whale).
