Priority 11: Enhance the temporal and spatial distribution and diversity of habitats to support all life stages of fish and wildlife species . The number of predator and prey in their “ecosystem” will be recorded and graphed which will show a predator prey cycle in an ecosystem. The completed graphic organizer will show students how the human population and economy depend on the environment for the majority of their basic needs. A dense population that is reduced in a density-independent manner by some environmental factor(s) will be able to recover differently than would a sparse population. Detrivore Students explore and discuss the direct and indirect impacts that ocean acidification can have on species, food web dynamics, ecosystem function, and commercial resources. Community and habitat go hand in hand: a habitat is where something lives, and a community is what lives there (but bear in mind that the habitat and community may focus on different organisms, as in the example above).

Define the following terms: population, community, ecosystem, biosphere, symbiosis, niche, habitat, conservation, threatened population data for humans within the park. Food Chain - A food chain is the series of organisms showing feeding relationships. Identify three reasons organisms need energy. If the fish are given more food, then they will be happier. When the prey population goes down then the predator doesn't have enough food and the prey population goes down. Define the following and give an example of each. Describe how both the population size and the rate of change of population vary over time. Predict what would happen to the rabbit population if the climate changed and the ecosystem only had snow a few months out of the year. How can life be studied at different levels? Compare the two objects and note similarities and differences between them.
