Which statement about nitrogen is FALSE?

1. Plants are the only organisms that need nitrogen
2. Nitrogen gas is abundant in our atmosphere

4. Plants need nitrogen to make proteins

When animals die and their bodies are not fully decomposed, they…

1. turn into fossil fuels
2. turn into water
3. turn into soil
4. evaporate

Nitrogen Fixation:

1. The process by which nitrogen in the atmosphere is changed into a form that can be used by plants
2. The large source of carbon-based compounds found within natural and engineered, terrestrial and aquatic environments
3. Life
4. The movement of nitrogen through living and nonliving things

Which statement explains the most realistic way to model energy flow in an ecosystem?

1. A food chain is most realistic because many organisms eat one type of food, and energy moves through a single pathway
2. A food chain is most realistic because many organisms eat a variety of foods, and energy moves through different pathways
3. A food web is most realistic because many organisms eat one type of food, and energy moves through a single pathway
4. A food web is most realistic because many organisms eat a variety of foods, and energy moves through different pathways

The energy provided by the sun is captured in the cells of this organism.

• Algae
• Shrimp
• Bacteria
• Water

This organism helps other organisms in multiple ways because of its outputs from cellular respiration and digestive waste.

• Algae
• Shrimp
• Bacteria
• Water

Which of the following statements is TRUE about energy in an ecosystem?

• Energy can be recycled in the same way as matter
• All energy disappears from the Earth when used, which is why we need the sun
• Every 1 pound an organism consumes creates about 10 pounds of biomass for the next organism
• About 10% of energy in living things is transferred to the next living thing when eaten

Which statement best reflects what would most likely happen if shrimp were removed from the ecosphere?

• Everything would die
• Bacteria would experience an exponential increase in population
• Bacteria and algae would both decrease, and the water would become dirty
• Algae population would increase until it reaches its carrying capacity

What statement is most true about MATTER in the ecosphere?

• It must be continuously supplied from the outside
• It is constantly being cycled within the ecosphere by the inputs and outputs of each organism
• It is cycled within the ecosphere, but organisms aren’t involved - it’s only from the environment
• It is being cycled both in and out of the ecosphere

• True/False: If autotrophs were destroyed, it would not have as great of an effect on the food web because heterotrophs would have more food for themselves.
