B2 Interdependence

HideShow resource information
An ecological niche describes...
The habitat that an organism lives in and its role in the habitat
1 of 12
Organisms that share similar niches are more likely to compete as...
They require similar resources
2 of 12
Interspecific competition is between...
Organisms of different species
3 of 12
Intraspecific competition is between...
Organisms of the same species
4 of 12
Why is intraspecific competition more significant?
Because the organisms share more similarities and so need same resources
5 of 12
Cycle of the population of predator and prey..
Population of prey increases -> Population of predators increase -> Number of prey decreases -> Predators starve and population decreases ->
6 of 12
Why are the predator-prey cycles always out of phase with each other?
It takes time for one population to respond to changes in the other population, e.g. takes time to reproduce
7 of 12
What do parasites do?
They feed on or in another living organism (the host) which suffers as a result of the relationship
8 of 12
Two other parasites are...
1) Fleas 2) Tapeworm (feeds on digestive system of various animals)
9 of 12
What is mutualism?
When both organisms benefit as a result of their relationship
10 of 12
Example of mutualism...
Insects and flowers...Insects receive sugary nectar from flower and insects help with pollination for flowers
11 of 12
Example of mutualism...
Cleaner fish (coral reefs) and larger fish...Coral reef gain food and larger fish get parasites removed from them
