if a chemical was placed in the water that caused all of the mosquito larvae to die, what would be one possible change in the food chain?

answer:

the population size of the predator of mosquitoes would increase.

explanation:

since the chemical kills the mosquito larvae, the mosquitoes’ population size would be reduced. it would have following possible effects on food chain:

a) in absence of their food (mosquitoes), the predator of mosquitoes will starve. so, the population size of the predator would be reduced.

b) also, the population size of the organisms that serve as food for mosquitoes would be increased due to absence of their predators (no mosquitoes in the system).

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
