A sequence of biotic changes that regenerate or create an ecological community is known as?.
harina [27]

A sequence of biotic changes that regenerate or create an ecological community is known as ecological succession.

Ecological succession is the process of change in an ecological community's species composition over time. The time frame can span several decades or fewer (for instance, following a wildfire). The community grows through an increase in complexity from a small number of pioneering plants and animals to a stable or self-sustaining climax community.

Succession is a process that occurs after a disturbance or the early colonization of a new environment. It involves changes to an ecological community that are more or less predictable and orderly. Secondary succession refers to succession that occurs after a pre-existing community has been disrupted, whereas primary succession refers to succession that starts in new environments with no impact from pre-existing groups.

To know more about ecological succession, refer to the following link:

Using the attached figure, what statement is true? Genetics382FlowerTreeExercise06.pdf 92 KB Genetics382FlowerTreeExercise06.pdf
Lesechka [4]

Answer:

The correct answer is option B. "Flowers on Peak 1 and flowers on Peak 4 are genetically identical".

Explanation:

Phylogenetic trees are graphical representations of the relationships among species, at which the closer two organisms are, the closer they are put together in the tree. Modern phylogenetic trees are constructed based on the anaylsis of genetic material, usually mitochondrial DNA. In this case, flowers with different phenotype and genotype were classified in a phylogenetic tree. Since flowers on peak 1 and flowers on peak 4 are grouped together it is safe to assume that the two organisms are genetically identical. I attached the missing figure.
