The study of organisms and their environment
What is Ecology
Animals that depend on outside temperatures
What are ectotherms?
Organisms that make their own food
What are autotrophs?
Movement from high to low concentration
What is diffusion?
The process where better-adapted organisms survive
What is natural selection
Nonliving factors like temperature and salinity
What are abiotic Factors
Animals that make their own body heat
What are Endotherms
Organisms that eat others for energy
What are heterotrophs?
Movement of water across a membrane
What is osmosis?
Maximum population an area can support
What is carrying capacity?
A group of the same species in one area
What is a population?
Body shape that reduces water resistance
What is Streamlining
Movement of energy between organisms
What is a food chain?
A membrane that lets some things pass
What is selectively permeable?
Competition within the same species
What is intraspecific competition?
The role an organism plays in its ecosystem
What is a Niche
Being nearly invisible to blend in
What is transparency?
Many connected food chains
What is a food web?
Using energy to move substances
What is active transport?
Competition between different species
What is interspecific competition?
All living and nonliving parts of an area together
What is an Ecosystem
Force that increases with ocean depth
What is Pressure
Process using sunlight to make food
What is photosynthesis?
Organisms that keep salt and water balanced
What are osmoregulators
Gradual change in species over time
What is evolution?
