Chapter 12: Interactions within Ecosystems SC 7-4.1 Summarize the characteristics of the levels of organization within ecosystems (including populations, communities, habitats, niches, and biomes).
Organisms occupy specific living areas All living thins depend on their environment to meet their needs. The type of living things you see in one specific area are determined by the characteristics of the area. Scientists group living things based on similar characteristics. Species- A group of living things that are so closely related that they can breed with one another and produce offspring that can breed as well.

Population Population-All of the individuals of a given species in a specific area or region at a certain time In the study of ecology, members of the same species that live in different areas belong to different populations. A biological population can be a group of animals, plants, bacteria, or fungi. Populations of many different species will be found living the same area. Members of a population compete for food, water, space, and mates
Communities Community- a group of populations that live in particular area and interact with one another. In a community, different plants, animals, and other organisms interact with each other. Ex. Cacti, iguanas, and crabs are part of the Galápagos' Island community.
Habitats and NICHES Habitat-The place where an organism lives so it can obtain food, water, shelter and other things needed for survival Habitats have certain physical characteristics that describe them. Including the amount of precipitation, temperature, and the soil quality. The habitats characteristics determine what type of species might live there. The particular role of an organism in its environment including type of food it eats, how it obtains its food and how it interacts with other organisms is its niche. Ex: the niche of a bee is to pollinate flowers as it gathers nectar for its food.
Biomes Individual ecosystems grouped together according to the climate and most of the vegetation and named by adaptations of organisms to that environment. Each ecosystem has organisms that have specific places where their needs are met and specific roles there. Ex. Taiga, tundra, dessert, tropical rain forest, temperate forest,
Organization of Environment. Biome- General area where organisms live in term of climate and types of plants. Ecosystem- Many ecosystems are found in each biome. Both living and nonliving factors interact to form a stable system. An ecosystem is smallest than a biome and includes only organisms and their local environment. Community- Consists of the living components of the ecosystem. In a community, different plants, animals, and other organisms interact with each other. Population- A population is a group of organisms of the same species that live in the same area. Organism- An organism is a single individual living thing such as an animal, plant, fungus, protisits, or bacteria,
