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.

3

Habitat & Niche• Habitat is the place a plant or animal lives

• 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?

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)

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

Levels of Organization- Biological

• Atom• Molecule• Organelle• Cell• Tissue• Organ• System

17

Levels of Organization- Ecological

• Ecologists have organized the interactions an organism takes part in into different levels according to complexity.

18

1st Level of Organization• Organism:

An individual living thing

19

2nd 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.

20

3rd Level of Organization• Community:

All the populations of different species that live in the same place at the same time.

21

4th 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)

22

5th Level of Organization

• Biosphere:The portion of Earth that supports life.

23

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.

Climate and biomes

• The typical weather patterns over a long period of time is the climate.

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
