Ecosystems Flashcards
What are species?
Organisms which interbreed to produce fertile offspring belong to the same species
What is biodiversity
Biodiversity refers to the range of different species present in an ecosystem
What is population
Population is a group of organisms in the same species
Define producer
A producer is an organism which can make food on its own in the process of photosynthesis. Producer are found at the start of food chain
What is a consumer
A consumer is that organism which must eat to obtain food. Primary consumer is the first animal in a food chain that eats producers
What is a herbivore
A herbivore is an animal that eats plants
What is carnivore
An animal that eats meat/other animals
What is a omnivore
An omnivore is an animal which eats both plants and other animals
What is a predator

What is a food chain
Food chain is a diagram which illustrates a feeding relationships. A producer is always found at the start, followed by a primary consumer then secondary consumer
What is a food web
A food web is a more complex diagram in which several food chains are linked. It illustrates a variety of predator and prey relationships
What happens when one organism is removed from a food web
It will affect other organisms
When does competition occur in the ecosystems
Competition occurs when resources are in short supply
What do organisms compete for
Organism might compete for food, habitat/territory/space, mates, water, light (plants)
When does infer specific competition occur?
Interspecific competition occurs amongst individuals of different species for one or a few of the resources they require.
What is intra specific competition
Intra specific competition is between members of the same species competing and is for all resources required as member of the same species required the same resources.
What is ecosystems
An ecosystem consists of all the organisms living in a particular habitat and the non living components with which the organisms interact
