PPT-4.1 Species, communities and ecosystems

The continued survival of living organisms including humans depend on sustainable communities Understandings Species are groups of organisms that can potentially interbreed to produce fertile offspring. A . community . is a local . assembly . of species that potentially interact.. Generally these species are on the same . trophic level. .. A community of species with similar niches is called an ecological . Chapter 22. E6.1 Illustrate how community change may involve succession over time which leads to changes in the mixture of species. Resources and energy available influence productivity of a community. Basics. Community: Organisms in a specific group of interacting producers, consumers, and recyclers that share a common living space.. Population: A group of organisms of the same species that occupy a specific area. . Assessment Statements. Define species, habitat, population, community, ecosystem, and ecology.

Let’s start big picture: what can governments and groups do?. Governments and Groups. Example: Lake Erie. In the 1970s, Lake Erie was full of sewage, farm chemicals and industrial chemicals. Organism ecology . = . relationship between organism and physical environment. . Population ecology. . =. investigates the dynamics of population change. Community ecology. . =. focuses on patterns of species diversity and interactions. Ocean Acidification: . How does changing ocean chemistry affect ocean ecosystems?.

Firetree was incl What is . Biodiversity. ?. It is the variety of earth’s species, the genes they contain, the ecosystems in which they live, and the ecosystems processes such as energy flow and nutrient cycling that sustain all life.. The best way to preserve an ecosystem is . by . rewilding. Basic terms. Trophic cascade . – Predators influence the abundance and behavior of prey. Prey abundance can be reduced if there are predators nearby, or prey can hide or move further. When the influence of a predator on its prey is so large that it reduces the trophic level at another level of the food chain (which affects the density of prey, in our case – vegetation), this is called a trophic cascade. .
