You need to make a double line graph. Make one line the number of the polar bears and the other the number of the seals. the number of the animals goes on the left side of the graph and the number of years goes on the bottom. graph your points for each and connect them with a line. make sure that your lines are different colors. it also needs a title. I hope I helped.
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.

Linnaeus' hierarchical system of classification includes seven levels. They are- from smallest to largest- species, genus, family, order class, phylum, and kingdom. A genus is a group of closely related species.
Answer:
consume other organisms because they can't perform photosynthesis.
Perform photosynthesis because they have chloroplasts.
Decompose decaying matters because they evolved to do that.
The anterior rami of the brachial plexus are the continuations of the anterior rami of spinal nerves C5-T1 . These rami emerge from the intervertebral foramina and travel through the neck. The five rami unite to form the superior, middle, and inferior trunks in the posterior triangle of the neck. Nerves C5, C6 unite to form the superior trunk; nerve C7 remains as the middle trunk; and nerves C8,T1 unite to form the inferior trunk. Portions of each trunk divide deep to the clavicle into an anterior and a posterior division. These primarily contain axons that innervate the anterior and posterior parts of the upper limb. Upon reaching the axilla, they converge to form three cords.
