A: Members of the same species, members of different species with similar needs.
Q: What is a morphological adaptation?
A: Structural adaptations eg. fur color, height, organ size.
Q: What is a behavioural adaptation?
A: Adaptations in habits, eg. nocturnal, food preference; mostly applies to animals.
Q: Give examples of factors which limit population size.
A: Predation, Disease, Pollution, Competition.
Q: What is biodiversity?
A: The number of different species in a particular area.
Q: What type of organism needs light and why?
A: Plants; they need it to make food for energy.
Q: Why is biodiversity good?
A: Better for scienctific and leisure purposes, stabler food chain, More medicines to be discovered, Ancient breeds can strengthen disease-resistance of new ones.
Q: What type of organism needs food and why?
A: Animals; they need it for energy.
Q: Where do arrows go on a food group?
A: From the food to the eater.
Q: What type of organism needs water and why?
A: All living organisms; they need it for chemical reactions that take place in cells.
Q: Why does biodiversity stabilise food chains?
A: The more biodiversity there is in an area, the more options each species has if a food source is wiped out.
Q: What type of organism needs oxygen and why?
A: All aerobically-respiring organisms; They need it to break down food to release energy.
Q: How can biodiversity be maintained?
A: Breeding and release programs, conservation and re-creation of habitats, control of invasive species, controlling threatening factors, legislation against damaging habitats or killing species.
Q: What type of organism needs carbon dioxide and why?
A: Plants; they need it for photosynthesis.
Q: What are problems with legislation to maintain biodiversity?
A: Wildlife needs may conflict with human needs, it can be difficult to cover all situations fairly.
Q: What type of organism needs minerals and why?
A: All living organisms; they need it for particular chemical reactions that take place in cells.
Q: What is compettion?
A: The competition of various organisms for the resources they need to survive.
Q: What is a sample?
A: An area of environment used to estimate numbers of species in an larger habitat.
Q: Between whom does competition occur?
A: Members of the same species, members of different species with similar needs.
