Answer:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Explanation:
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.
The best answer to the question stated above is letter C.<span>The moon's orbit must cross the plane of the ecliptic.</span>

>>E</span><span>arth's orbit is called the ecliptic plane as the Moon's orbit must cross this plane in order for an eclipse (both solar as well as </span>lunar) to occur
Answer:In ecology, a niche is the match of a species to a specific environmental condition. It describes how an organism or population responds to the distribution of resources and competitors and how it in turn alters those same factors.
Explanation:
Earth is always rotating around the sun that means if it were winter on one side of the world, (that is not on the side of the sun) the other side of the world would be summer, ( the side that the sun is shining on)
