Evolution can be described as the change in the <u>allele</u> frequencies of a<u> gene pool </u>over time. The process of natural selection acts on specific <u>phenotypes </u>and causes a change in the frequency of the alleles that produce them. A population of organisms with similar phenotypes that interbreed is defined as a <u>species</u>. Note that<u> </u><u>species</u> evolve, not individuals.

Explanation:

Evolution is the gradual change in species over time due to selective response processes.

Natural selection of species leads to overproduction of species, variation or habitability of heritable characteristics, selection of inherited traits or phenotypes which aid the species to better suit to their environment, and to enhance and maintain the species fitness to survive and thrive in their environment.

Natural selection leads to genetic drift or shift in the gene pool to develop favorable phenotypes under random circumstances through bottleneck or founder effects.

The frequency distribution of phenotyes follows a bell curve due to either directional, stabilizing, or disruptive natural selection processes. The group or population with similar type of traits or phenotypes which can interbreed among themselves are collectively called as species.

The evolutionary changes are exhibited or observed in the species as a whole and not in an individual organism due to evolutionary processes like co-evolution, divergent and convergent evolution.

The primary producers in an ocean grazing food web are usually ________.
Butoxors [25]

Answer:

phytoplankton

Explanation:

Phytoplankton can be defined as a set of photosynthesizing microorganisms that live floating on the water surface. It is composed of microscopic algae and cyanobacteria, which can be unicellular, colonial or filamentous. These microorganisms are defined as the primary producers of an ocean grazing food network.

Because phytoplankton live in aquatic environments - both in limic (eg lakes) and marine environments - they have a number of adaptations that guarantee their survival in the water column.  Some of these microorganisms, for example, have flagella that aid locomotion; others, in turn, have gas vacuoles that aid in flotation, while some of them have mucilage, which surrounds the cells and ensures protection, flotation and locomotion.
