8. What elements are missing from this
food web?
A biome is a group of land ecosystems with similar climates and organisms. The six major
biomes that most ecologists study are the rain forest, desert, grassland, deciduous forest,
boreal forest, and tundra.
Tropical Rain Forest – Tropical rainforests are found in regions close to the equator. The
climate is warm and humid all y ear long, and there is a lot of rain.
Desert – Deserts receive less than 25 centimeters of rain per year. They often undergo large
shifts in temperature during the course of a day.
Grassland – Grasslands are areas that are populated mostly by grasses and other non-woody
plants. Most grasslands receive 25 to 75 centimeters of rain each year. Fires and droughts are
common in this biome.
Deciduous Forest – Deciduous forests contain deciduous trees, which are trees that shed their
leaves and grow new ones each year. They receive enough rain to support the growth of trees
and other plants, at least 50 centimeters each year. Temperatures in the deciduous forest vary
greatly during the year.
Boreal Forest – Most of the trees in the boreal forest are coniferous trees, trees that produce
their seeds in cones and have leaves shaped like needles. Winters in these forests are very
cold, and summers are rainy and warm.
Tundra – The tundra is an extremely cold and dry biome, and it may receive no more
precipitation than a desert. Most of the soil in the tundra is frozen all year long; this frozen
soil is called permafrost.
Choose one of the above biomes: _______________________________________________
Producers (at least 4)
Consumers (at least 8)
Decomposers (at least 2)
1. Use the organisms from your biome to create a food chain which includes at least 3
organisms. Be sure to include the names of the organisms and which energy role they fill
(producer, first-level consumer, etc.).
2. Now use the organisms from your biome to create an energy pyramid which includes at least 4
organisms. Include the name and a picture of each organism, which energy role they fill, and
how much energy is available at each level.
3. Finally, use the organisms from your biome to create a food web which includes at least 10
organisms. Be sure to include names of the organisms and energy flow arrows (pointing in the
correct direction).
