2 What is Ecology?? The study of interactions that take place between organisms and their environment. The study of interactions that take place between organisms and their environment. It explains how living organisms affect each other and the world they live in. It explains how living organisms affect each other and the world they live in.

3 Habitat & Niche Habitat is the place a plant or animal lives Habitat is the place a plant or animal lives Niche is an organism’s total way of life Niche is an organism’s total way of life

Fundamental vs. Realized Niche

What does abiotic mean? What does the prefix ‘a’ mean? What does ‘bio’ mean? 5

6 The Nonliving Environment Abiotic factors- the nonliving parts of an organism’s environment. Abiotic factors- the nonliving parts of an organism’s environment. Examples include air currents, temperature, moisture, light, and soil. Examples include air currents, temperature, moisture, light, and soil. Abiotic factors affect an organism’s life. Abiotic factors affect an organism’s life.

So then what would ‘biotic’ mean? 7

8 The Living Environment Biotic factors- all the living organisms that inhabit an environment. Biotic factors- all the living organisms that inhabit an environment. All organisms depend on others directly or indirectly for food, shelter, reproduction, or protection. All organisms depend on others directly or indirectly for food, shelter, reproduction, or protection.

Checkpoint Predict what types of things scientists would study if they were analyzing biotic factors in an ecosystem. Be specific (do not just say living things)

Circle of Life From the video, write down all biotic interactions you saw and any abiotic/biotic interactions you saw.

16 Levels of Organization- Biological Atom Atom Molecule Molecule Organelle Organelle Cell Cell Tissue Tissue Organ Organ System System

17 Levels of Organization- Ecological Ecologists have organized the interactions an organism takes part in into different levels according to complexity. Ecologists have organized the interactions an organism takes part in into different levels according to complexity.

18 1 st Level of Organization Organism: An individual living thing Organism: An individual living thing

19 2 nd Level of Organization Population: A group of organisms, all of the same species, which can interbreed and live in the same place at the same time. Population: A group of organisms, all of the same species, which can interbreed and live in the same place at the same time.

20 3 rd Level of Organization Community: All the populations of different species that live in the same place at the same time. Community: All the populations of different species that live in the same place at the same time.

21 4 th Level of Organization Ecosystem: Populations of plants and animals that interact with each other in a given area with the abiotic components of that area. (terrestrial or aquatic) Ecosystem: Populations of plants and animals that interact with each other in a given area with the abiotic components of that area. (terrestrial or aquatic)

22 5 th Level of Organization Biosphere: The portion of Earth that supports life. Biosphere: The portion of Earth that supports life.

23 The Biosphere Life is found in air, on land, and in fresh and salt water. Life is found in air, on land, and in fresh and salt water. The BIOSPHERE is the portion of Earth that supports living things. The BIOSPHERE is the portion of Earth that supports living things.

Climate and biomes The typical weather patterns over a long period of time is the climate. Copyright Cmassengale

Biomes are a group of ecosystems with similar climates (temperature and rainfall) and organisms.

Biome Brochures You are going to make a travel brochure for a biome. In your brochure include: – Summary of the climate in your biome – Map where your biome is found – Main abiotic factors that affect life (w/ pictures) – Main biotic factors (flora and fauna) (w/ pictures) – Two specific biotic interactions – At least 1 graph that summarizes your biome – An example of a habitat and niche for an organism in your biome
