Biology Flashcards
Adaptation
Adaptations are characteristics that help an organism to survive and reproduce.
Competition
Animals compete for food, water, space, shelter, minerals and mates to reproduce with.
Environmental changes
Plants and animals adapt to changes in their environments. This could be due to changes through fire, climate change, or disease, causing reduced food supplies.
Competition and adaptation
Predator and prey species are interdependent,
One pop directly affects another pop
Variation
Differences in characteristics
Inherited variation
Characteristics that are passed on from parent to offspring.
Environmental variation
Surroundings affect your characteristics
Can be affected by both

Discontinuous Variation
Can only result in certain values and is plotted on a bar chart
Continuous Variation
