What is Ecology??• 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.

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

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

So then what would ‘biotic’ mean?

The Living 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.

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)

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

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

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
