Why do you think there is a basic difference between the kinds of fertilization most common in aquatic and terrestrial animals?

Ans.

Fertilization involves fusion of sperm (male gamete) and egg cell (female gamete) to form zygote.

In aquatic animals, external fertilization takes place, during which both eggs and sperms are released into the water and their fusion takes place. The aquatic environment protects the eggs and sperms from drying out.

As their is no way or carrier to transfer sperms and eggs in Terri's trial environment, in those animals, fertilization is internal, in which sperms are inserted to the female body, where they fuse with egg cell.

Thus, the basis difference between marine and terrestrial organism is that marine organisms show external fertilization, while land animals show internal fertilizer.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

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)
