Ecology
The study of the interactions that take place among organisms and their environment
Biosphere The part of Earth that supports life Top portion of Earth's crust All the waters that cover Earth's surface Atmosphere that surrounds Earth.
Ecosystem Biotic Parts Abiotic Parts Plants Animals Bacteria Fungi Atmosphere Soil Water
Population All the organisms in an ecosystem that belong to the same species Maple Trees Robins Earthworms
Community All the populations in an ecosystem Deciduous Forest Maple trees Oak trees Pine trees Robins Rabbits
The place in which an organism lives Habitat The place in which an organism lives provides the kinds of food and shelter, the temperature, and the amount of moisture the organism needs to survive Describe the habitat in the next slide.
Niche An organism’s job or importance in an ecosystem (ex: autotroph, carnivore) Each niche can only be filled by one organism or there will be competition.
Competition Two or more organisms want the same resources in the same ecosystem Food Mates Water habitat Only one can win!! Unless the other organism is able to migrate to another area it will perish.
Competition Limits Population Size Population Size may vary over time but there is a limit to the number of a specific kind or organism that can live in an ecosystem. This is called the Carrying Capacity
Limiting Factor Anything that restricts the number of individuals in a population. (food, water, habitat) Includes living and nonliving features of the ecosystem What do you think is the limiting factor in the next slides?
Biodiversity
Biodiversity-the variety of different species from the six kingdoms in an ecosystem.
What types of organisms can you identify in this ecosystem?
Secondary Succession
Pioneer species A group of organisms, such as lichens, found in the primary stage of succession and that begin an area's soil-building process
Climax community A community that has reached a stable stage of ecological succession
Biome Large geographic areas with similar climates and ecosystems
Includes Tundra Taiga Desert Temperate deciduous forest Temperate rain forest Tropical rain forest, and grassland
