  1. The levels of the environment

  2. Ecology- is the study of the relationships between organisms and their environment. • Consists of: plants, animals, soil, sunlight, temperature, amount of water. • Ecologists- are the scientists that study these interactions. Ecology

  3. Environment- everything that affects an organism. (BOTH: biotic & abiotic factors) environment

  4. Structure of the Environment: • Organism • Population • Community • Ecosystem • Biosphere

  5. 1. First level is an individual Organism. 1. Organism

  6. 2. Population 2. The second level is made up of a group of similar organisms who share the same area.

  7. 3. The third level, a Communityis made up of different populations that live in the same area. • How the deer interact with the plants. • How the cougars interact with the deer. 3. Community

  8. 4. The fourth level, an Ecosystem is a community together with its nonliving (abiotic) environment. • Consists of: plants, animals, soil, sunlight, temperature, amount of water. 4. Ecosystem

  9. 5. Biosphere – is made up of all ecosystems on Earth 5. Biosphere

  10. Producers • Producers use sunlight directly to make food. Ex) plants. • Photosynthesis is the process through which plants make their food ; using sunlight, water & carbon dioxide.

  11. Consumers • Consumer- Organisms that cannot make their own energy. • Consumers get their energy by eating other organisms (producers & consumers).

  12. types of consumers: • Herbivore – a consumer that eats plants. • Omnivore – a consumer that eats both plants and animals. • Carnivore – a consumer that eats animals. • Scavengers – animals that feed on the bodies of dead animals.

  13. Decomposers – organisms that get energy by breaking down the remains of other animals. They get energy by reducing them into simpler forms of matter (h20 and CO2). Decomposers

  14. Food Chain- a simple model of the feeding relationship in our ecosystem. Energy flow in ecosystems…

  15. Food Web- a series of overlapping food chains in an ecosystem. Energy flow in ecosystems… “Desert Food Web”
