Ecology Unit Study Guide

Select the correct order of the levels of organization from organism through biosphere.

• Organism, population, community, ecosystem, biosphere

• Biosphere, ecosystem, community, population, organism

• Organism, community, population, ecosystem, biosphere

• Population, organism, community, biosphere, ecosystem

All the biotic and abiotic factors in an area make up a:

• community

• ecosystem

• population

• habitat

What two abiotic factors are most important in determining biomes?

• Temperature and precipitation

• Soil and sunlight

• Wind and humidity

• Altitude and latitude

Most of Michigan is found within which biome?

• Desert

• Tundra

• Temperate Forest

• Grassland

Plants use which process to convert energy from sunlight? Also, what are the inputs and outputs of this process?

• Photosynthesis; Inputs: sunlight, carbon dioxide, water; Outputs: glucose, oxygen

• Respiration; Inputs: glucose, oxygen; Outputs: carbon dioxide, water, energy

• Fermentation; Inputs: glucose; Outputs: ethanol, carbon dioxide, energy

• Transpiration; Inputs: water; Outputs: water vapor

Most of the energy in ecosystems is provided by which organisms?

• Producers

• Consumers

• Decomposers

• Herbivores

Almost all producers get their energy from:

• the sun

• the soil

• other animals

• the wind

Each of these animals eats in which place?

• Forest

• Ocean

• Desert

• Mountain

A trophic pyramid is best represented by which of the following diagrams?

• A pyramid with producers at the base and top predators at the apex

• A circle with all organisms at the same level

• A straight line with producers and consumers side by side

• A random arrangement of organisms

Energy is lost as it is passed between trophic levels (or food chain levels) mainly as:

• Heat

• Light

• Sound

• Electricity
