Answer:
In the freshwater food web,
the relationship between the minnow and the water fleas can be described as <u><em> Predator-prey relationship</em></u>
Explanation:
A food web can be described as a diagram which shows multiple food chains. It represents the 'predator-prey' relationship in an ecosystem.
The freshwater food web will described all the predator-prey relationships in the fresh water.
The minnows in the fresh water feed on larval fishes, mosquito larvae and water fleas. Hence, minnows will be the predators and water fleas will be the preys. So, these organisms will show a predator-prey relationship.
These two organisms may have evolved by coevolution. The last option in the given question is the correct option. The Latin-American humming birds had to evolve as per their surroundings, otherwise they would have become extinct in that region. For that sole purpose they had to have the long and curved bills. The flowers needed the humming birds for their pollination. To attach with the legs of the humming birds in the region, the flowers had to become sharply curved. The humming birds had to come in contact with the flower while sucking the nectar. this helped the plants in their pollination process. so both became mutually beneficial to each other.
