tion?
2. What is a commu- A community is all the different populations of different species living in an area
nity?
3. What is an The interaction of a community with non-living (abiotic) parts of the environment.
ecosystem?
4. Link the terms An individual is a part of a species.
species, habitat, A species lives in a habitat within a population.
population and Many different populations interact in the same habitat, forming a community.
community to- An ecosystem is the interaction of a community with non-living abiotic factors.

5. Name 4 abiotic Temperature, light intensity, water levels, pollutants
factors that affect
a community
6. Explain how tem- Temperature affects the rate of photosynthesis.
perature affects a The rate of photosynthesis affects the rate at which the plant grows
community? Plants can be food sources or shelter for many organisms.
7. Explain how light Light is required for photosynthesis

11. How does wind - wind intensity affects the rate of transpiration
intensity and di- - transpiration affects the temperature of the plant, as well as the rate of photo-
rection affect a synthesis as the leaves need water and mineral ions
