Objective: Use the study of biomes to show knowledge and comprehension about biotic and abiotic factors, food chains, food webs, energy pyramids, symbiotic relationships, and limiting factors in an environment.
YOUR ASSIGNED BIOME = __________________________________
Instructions:
On a blank sheet of poster paper (provided), draw a scene from your assigned biome.
You must include both BIOTIC and ABIOTIC factors.
You must include at least 2 producers, 2 primary consumers, 2 secondary consumers, and at least 1 tertiary consumer.

Draw and indicate one predator-prey relationship
Draw and indicate one symbiotic relationship. Also indicate the TYPE of symbiotic relationship it is.
List three density dependent limiting factors and three density independent limiting factors for ONE animal population in your biome. (Make sure to indicate which animal population you choose.)
List the abiotic characteristics of your biome neatly in the corner (preferably in a chart). This should include the temperature, rainfall, and physical characteristics of your biome.

Staple this paper to your poster when both are complete.
Essay Questions
Answer the following three questions in essay format:
1. What is the difference between how nutrients and chemicals are replenished in an ecosystem and how energy is replenished within an ecosystem?
