Places where an organism lives
biodiversity
The variety of species that exist on earth
community?
All the living organisms in a habitat
population?
All the organisms of a species
species
Population that can be interbred to produce fertile offspring
ecosystem
All the living organisms and the non-living factors they interact with
producer
Organisms that make their own food (green plants)
consumer
Animals that get their food from eating plants or other animals that have eaten plants
herbivore
An organism that only eats plants
omnivore
An organism that eats animal material and plants
carnivore
An organism that only eats animal material
predator
An animal that hunts other animals for food
prey
An animal that gets hunted by the predator
What do the arrows in a food chain show
The direction of energy flow
What do food webs and food chains show
The feeding relationships between organisms
What is the first and second consumers in a food chain called
Primary and secondary consumers
What does the removal of any species on a food web do to the other organisms
Cause them to increase, decrease or stay the same
Reasons for numbers of organisms changing include:
Having more/less food to eat
Having more/less predators eating them
What is a niche
The role an organism plays within a community
What does a niche involve
Competition
Predation
Conditions it can tolerate eg. Temp
When does competition occur
When resources are in short supply
What do animals compete for
Mates, food, habitat
What do plants compete for
Light, space, pollinators
What is interspecific competition
Competition between different species for some of the same resources
What is intra specific competition
Competition within the same species for all of the same resources
Which type of competition is more intense, why?
Intraspecific because they compete for ALL of the same resources
