__3___
b) grassland
__4___
c) boreal forest
__1___
d) temperate deciduous
forest
1) longer growing season, higher temperatures,
fertile soil, many large trees
2) low temperatures, short growing season,
permafrost
3) longer growing season, higher temperatures,
fertile soil, grasses
4) no permafrost, conifer trees, acidic soil
Short Answer Questions
1. How is cellular respiration related to photosynthesis?
Cellular respiration is the opposite process of photosynthesis. Photosynethesis is makes sugar
and oxygen out of carbon dioxide and water. Cellular respiration makes carbon dioxide and
water out of sugar and oxygen.
2. Why is there abundant life in shallow waters near the shore?
Shallow waters near the shore are nutrient rich and there is lots of sunlight for
photosynthesis for lots of plants. Lots of plants make good homes for small animals

3. Look at this simple food chain: grass rabbit  coyote. Could it be part of a food
web? Explain.
Yes it could be part of a food web because food webs contain many food chains. A food web
would show other animals that eat grass and other animals that eat the rabbit
4. Identify two human activities that can influence the carbon cycle.
Any of the following is an acceptable answer:
1) Humans respire and release carbon dioxide into the air
2) Humans burn fossil fuels which releases carbon dioxide into the ar
3) Humans decompose and release carbon back into the soil
Can you think of anything else?
5. What are the five key abiotic factors that determine which species can live in particular
aquatic ecosystems?
Light, nutrients, water temperature, acidity, salt levels
