A student performed an investigation in which two ivy plants were planted in two separate containers. One of the containers had earthworms mixed in with the soil, and the other container had soll and no earthworms. The plants were given the same amount of water and exposed to the same amount of sunlight.The student observed that after several weeks of growth, the plant exposed to earthworms appeared to be healthier and exhibited more growth.To conclude that the relationship between the plant and the earthworm is an example of mutualism the student must perform follow-up investigations that do which of the following? Determine whether the earthworms damage the soil in any way Determine whether the earthworms benefit from being with the plant Determine whether the water given to the plant is unpolluted Determine whether the other plant in the investigation suffers as a result of not being exposed to earthworms 10 points

Question

A student performed an investigation in which two ivy plants were planted in two separate containers. One of the containers had earthworms mixed in with the soil, and the other container had soll and no earthworms. The plants were given the same amount of water and exposed to the same amount of sunlight.The student observed that after several weeks of growth, the plant exposed to earthworms appeared to be healthier and exhibited more growth.To conclude that the relationship between the plant and the earthworm is an example of mutualism the student must perform follow-up investigations that do which of the following? Determine whether the earthworms damage the soil in any way Determine whether the earthworms benefit from being with the plant Determine whether the water given to the plant is unpolluted Determine whether the other plant in the investigation suffers as a result of not being exposed to earthworms 10 points

Answer 1

Determine whether the earthworms benefit from being with the plant.

Answer 2

## Step 1The problem is about the concept of mutualism in biology. Mutualism is a type of symbiotic relationship where both organisms involved benefit from the relationship. In this case, the student is investigating the relationship between an ivy plant and earthworms.## Step 2The student has already observed that the plant exposed to earthworms appears healthier and shows more growth. To confirm that this is an example of mutualism, the student must perform follow-up investigations.## Step 3The follow-up investigations should focus on determining whether the earthworms benefit from being with the plant. This is because mutualism requires that both organisms benefit from the relationship.## Step 4The other options, such as determining whether the earthworms damage the soil, whether the water given to the plant is unpolluted, or whether the other plant in the investigation suffers as a result of not being exposed to earthworms, are not directly related to the mutualistic relationship between the plant and the earthworms.
