Question

1. what are the producers in the food web? 2. what does the turtle eat? 3. what type of consumer is the turtle? 4. what type of consumer is the prawn? 5. what type of consumer is the frog? 6. what would happen to the snake population if the frog population decreased? 7. what would happen to the prawn population if the trout population decreased?

Explanation:

1. Producers are organisms that make their own food through photosynthesis. In the food - web, algae and waterweed are producers.
2. By looking at the arrows pointing to the turtle in the food - web, we can see it eats carp and slug.
3. The turtle eats plants (indirectly through plant - eating organisms like slug) and animals (carp), so it is an omnivore.
4. The prawn eats algae, so it is a primary consumer.
5. The frog eats dragonfly and slug, so it is a secondary consumer.
6. If the frog population decreases, the snake, which preys on the frog, will have less food, so the snake population will likely decrease.
7. If the trout population decreases, since trout preys on prawn, the predation pressure on prawns will be reduced, and the prawn population will likely increase.

Answer:

1. Algae, Waterweed
2. Carp, Slug
3. Omnivore
4. Primary Consumer
5. Secondary Consumer
6. Decrease
7. Increase
