A j-curve shaped graph means a given population started to grow rapidly in exponential form until for some reason it stops growing and decreases. The causes for this can be Seasonality of some species, Which growth peaks at a given season but at the change of seasons the environment is no more ideal for them and the growth starts decreasing. Other causes can be a population of organisms which breeding is so effective and numerous that in this phase they have exponential growth in their population.
The J-shaped<span> section of a time-series graph in which the </span>curve<span> falls into negative territory and then gradually rises to a higher level than before the decline. Basically think of a merry-go round</span>
The species that are mostly to be producers to be plants because they take in the light source aka the sun via photosynthesis. This takes up most of the energy in the ecosystem
A sample count is the data from a sample, or a small group. A total count would be the data from the entirety of whats being studied, not just a sample.
