A group of ecosystems with similar climates and organisms

• Biome
• Ecosystem
• Habitat

Part of Earth in which life exists including land, water, and air or atmosphere

• Lithosphere

• Atmosphere
• Biosphere

development at an increasingly rapid rate in proportion to the growing total number or size; a constant rate of growth applied to a continuously growing base over a period of time

• Exponential growth
• Linear growth
• Logarithmic growth
• Cubic growth

a small population starts to grow slowly then rapidly and then it levels off when the carrying capacity is reached

• Exponential growth
• Linear growth
• Cyclic growth
• Logistic growth

Largest number of individuals of a population that a environment can support

• Ecological footprint
• Population density
• Carrying capacity
• Biodiversity index

Limiting factors are things that prevent a population from growing any larger. For example, 10 rabbits may live in a habitat that has enough water, cover and space to support 20 rabbits, but if there is only enough food for ten rabbits, the population will not grow any larger.

• Water availability is a limiting factor.
• Predators are a limiting factor.
• Food availability is a limiting factor.
• Space is a limiting factor.
