Outcome One: Biological Diversity and Survival

Biological Diversity - Variety of species and ecosystems across the Earth

The closer you get to the equator, the more diversity, closer to the poles, less diversity
- This is because of warmer temperatures due to Earth's tilt
- A large amount of sunlight, which allows for more plants to grow and animals to survive

Components of Biological Diversity

Ecosystem Diversity - A variety of ecosystems around the world
- Mountain ecosystem can be near lake ecosystem in foothills area

Community Diversity - Differences between communities

Population Diversity - Differences between different populations of the same species
- Like different ages of two different herds of deer

Species Diversity - Differences occurring between individual organisms within same species
- Like dog breeds

Genetic Diversity - Small differences in DNA between individuals of a species
- you look different than siblings because of different combinations in DNA

Adaptations
- Feature that increases an organism's ability to survive in a particular environment

Behavioral Adaptations
- Something an animal does in response to something else to survive
- Ex. Bears hibernate during the winter

Structural Adaptations
- A physical characteristic that helps an organism survive
- Ex. Chameleons changing color to blend into the environment

Variations - Can look different in members of the same species

Variation within a population of a species is called variability
- It is vital if the environment changes drastically
- If there is great variation in a species, then most individuals will survive if there is change

, Arrangement of Species

Species
- Particular groups of organisms
- Have the same structure and can reproduce to make offspring

Population
- Members of the same species live in same area together and share all the resources
- Ex. herds

Community
- When different populations live in the same area
- Ex. living plants and animals of different species

Ecosystem
- Where biotic things interact with biotic and abiotic factors in an environment
- Ex. community at watering hole while plants absorb sunlight and water

Niches
- Role an organism plays in a particular ecosystem
- Can change depending on the environment and other organisms

What it includes:
● Habitat - Where it lives
● What it eats
● What eats it
● What it competes with
● How / When it reproduces
● Impact it has on the environment

Broad Niche
- Allows organisms to survive in many different conditions
- Generalists are organisms with adaptations to survive in variable conditions
- Ex. Cougars can live in mountains, foothills, prairies, and can depend on various food
sources

Narrow Niche
- Highly specialized role
- Specialists are organisms that adapt to specific environments
- Only eat and live in specific areas
- Ex. Pandas only live in Central China and only eat bamboo
