Multiple Select

The niche of an organism is best described as ...

• how it meets its needs for food and shelter

• how it survives, and how it reproduces

• The number of organisms in a community

Multiple Choice

What does every food chain start with?

• producers
• sun
• consumer
• decomposers

Multiple Select

Mark all the organisms that are considered producers

Multiple Choice

• carnivore

• omnivore

• herbivore

• decomposer

Multiple Choice

Mushrooms often grow around dead plants such as decomposing trees. They break down these dead organisms and put energy that stores in the plant back into the ground for other plants to use. What type of consumer are mushrooms?

• carnivore

• omnivore

• herbivore

• decomposer

Multiple Choice

• herbivore-producer-carnivore

• herbivore-carnivore-producer

Multiple Choice

• zooplankton

Multiple Select

Why is phytoplankton important - select all that apply:

• it is the basis for marine food webs

• provides 50% oxygen for life on earth

• removes detritus from environment

• removes excess CO₂ from atmosphere

• allows corals to build hard limestone structures

Multiple Choice

What is the best explanation for an energy pyramid?

Multiple Choice

Which of the following is an abiotic factor that affects marine ecosystems?

• Pressure
• Algae
• Pedators
• Food Web

Multiple Choice

An example of an abiotic factor influencing marine organisms is ...

• salinity

• predation

• parasitism

• competition

Open Ended

Algae & phytoplankton depend on sunlight and nutrients from water to survive. Suppose currents have been disrupted and upwelling has stopped. How will sharks be impacted this change?
