The producers in aquatic ecosystems include organisms in which of the following groups?

Biology
2 answers:
Misha Larkins [42]3 years ago

Answer: E

Explanation:

The primary producers of the aquatic food web are phytoplankon.

Phytoplankton are "photoautotrophs," harvesting light to convert inorganic carbon to organic carbon, and they supply this organic carbon to diverse "heterotrophs," organisms that obtain their energy solely from the respiration of organic matter.

Most phytoplankon are microscopic marine algae and Cyanobacteria . They are oxygenic photosynthetic bacteria. They harvest the sun's energy, absorb carbon dioxide, and emit oxygen. Like plants and algae, cyanobacteria contain chlorophyll and convert carbon dioxide to sugar through carbon fixation

Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water.

Answer:

e. All of the above are correct.

Explanation:

Cyanobacteria are primary producers in several aquatic ecosystems. Most lake organisms depend on algae as a primary food source. Other aquatic plants also serve as producers but not so much. Green plants and photosynthetic bacteria are all examples of photoautotrophs, which are primary producers in water.

A. A population with an annual growth rate of 3% doubles roughly every ____ years.
nikklg [1K]

Answer:

a.

3*x=100\\100/3=33.(3)\\\\

And you can round 33.(3) to 33.

b.

4*x=100\\100/4=25\\\\

and the final result is 25.

c.

7*x=100\\100/7=14.29\\\\

And you can round 14.29 to 14.

Explanation:

First of all, you have to find how many times the growth rate would multiply to get closer to 100%. So if you multiply 3 times 33 you'll get 99. So, a population with an annual growth rate of 3% doubles roughly every 33 years.

This solution is just for annual growth rate that is one year long.
