highly susceptible to (affected by) water pollution

foraging filter feeding
both neither

Explanation:

How moose eat

Moose are terrestrial animals. They move around (forage) to find food (like plants). So, this is related to foraging.

How mussels eat

Mussels are filter - feeders. They stay in one place (attached to rocks, etc.) and filter food (like plankton) from the water that moves.

Requires the animal to move while the food stays in one place

This is the definition of foraging. For example, a moose moves to eat plants that are stationary (in a sense, the plants don't move on their own in the way the moose moves).

Requires the food to move while the animal stays in one place

This is the definition of filter - feeding. Mussels (and other filter - feeders) stay in one place and food (in the form of small particles in water) moves to them.

Highly susceptible to (affected by) water pollution

Filter - feeders (like mussels) are highly susceptible. They filter water for food, so if the water is polluted, they take in the pollutants. Foragers (like moose, which eat plants) are not directly affected by water pollution in the same way (unless the plants are water - plants and the water is polluted, but generally moose are not as directly affected as filter - feeders).

Affected by human activities

Both foragers (e.g., moose can be affected by deforestation, habitat destruction) and filter - feeders (e.g., mussels affected by water pollution, habitat destruction in water bodies) are affected by human activities.

Studied by humans

Both foraging (e.g., in the study of animal behavior, ecology) and filter - feeding (e.g., in marine biology, ecology) are studied by humans.

Answer:

• How moose eat: foraging
• How mussels eat: filter feeding
• Requires the animal to move while the food stays in one place: foraging
• Requires the food to move while the animal stays in one place: filter feeding
• Highly susceptible to (affected by) water pollution: filter feeding
• Affected by human activities: both
• Studied by humans: both
