Question

making connections: directions: answer the questions in the yellow column on the right. notice some questions have multiple parts. use complete sentences to answer each part. be sure to elaborate fully on your answer and make connections to food webs and the lesson content. question your answer goes here in complete sentences! 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:

For question 5, if we choose rabbits in a grass - land ecosystem food web, their removal would mean a lack of food for predators like foxes and hawks, leading to a decline in their populations. Also, the plants that rabbits eat would over - grow. For question 6, an example of an omnivore could be a raccoon. It is an omnivore because it eats both plants (berries) and animals (insects and small rodents) as shown in the food web. For question 7, examples of relationships where one species is harmed are predation (a lion preys on a zebra, harming the zebra) and parasitism (a tick on a dog, harming the dog). For question 8, examples of relationships where one species benefits and no species is harmed are mutualism (bees and flowers, bees get nectar and flowers get pollinated) and commensalism (a bird building a nest in a tree, the bird benefits and the tree is not affected).

Answer:

1. If rabbits were removed from a grass - land ecosystem food web, predators like foxes and hawks that rely on them for food would decline in number, and the plants that rabbits eat would over - grow.
2. A raccoon is an omnivore.

6a. A raccoon is an omnivore because it eats both plants such as berries and animals such as insects and small rodents as shown in the food web.

1. Predation (lion preying on zebra), Parasitism (tick on dog).
2. Mutualism (bees and flowers), Commensalism (bird building nest in tree).
