Chapter 13 Homework

During which time period was the growth of fish captures greatest?

Choose the likeliest explanation for the trend shown in the graph in step 2.

Compensation depth is the depth in the ocean where the photosynthetic rate exceeds the rate of cellular respiration.

The products of photosynthesis are carbon dioxide (CO2) and water (H20).

Nitrogen and phosphorus concentrations have no impact on primary productivity rates in marine ecosystems.

An overabundance of oxygen results in eutrophication.

Diatoms are classified as members of the division chlorophyla.

Primary productivity is equal to the amount of photosynthesis plus the amount of respiration.

Primary productivity in temperate marine systems is limited solely by the amount of available solar radiation.

Equatorial upwelling decreases primary productivity in tropical waters.

Primary producers, herbivores, and carnivores are all examples of trophic levels within a food chain or food web.

Energy flow in photosynthetic marine ecosystems is unidirectional in contrast to nutrients, which cycle through ecosystems.

Match the organism with its correct descriptor of energy use or trophic level: Algae

Match the organism with its correct descriptor of energy use or trophic level: Dolphin

Match the organism with its correct descriptor of energy use or trophic level: Maximum substantial yield
