Biology

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.

What causes ocean water near the equator to be warmer than ocean water<br> farther north?
ASHA 777 [7]

Answer: The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as the sun's rays hit them directly. :)

How would the body most likely respond to the condition illustrated
Mashutka [201]

Answer:

A) Faster blood flow: A faster blood flow means the heart pumps blood with more power. Pumping blood to fast for too long can damage the heart muscle and interfere with its normal electrical signals, which can result in a dangerous heart rhythm disorder.

B) Infection: infection is caused by invasion of the body by external microorganisms. Disease can arise if the host's protective immune mechanisms are compromised and the organism inflicts damage on the host.

C) vomiting: This is an involuntary, forced expulsion of stomach contents usually through the mouth or nose. Body's reaction can be aspiration, electrolyte and water loss, damage to the enamel of the teeth, tear of the esophageal mucosa etc.

D) High blood pressure: This is due to the heart pumping blood at high pressure putting a strain on the walls of the blood vessels. In some cases, people with high blood pressure may have a pounding feeling in their head or chest, a feeling of lightheadedness or dizziness, or other signs.

Tell me what you think of adolescence as toddlerhood of adulthood ​
trapecia [35]

Answer:

Adolescence is the period of transition between childhood and adulthood. It includes some big changes—to the body, and to the way a young person relates to the world.

The many physical, sexual, cognitive, social, and emotional changes that happen during this time can bring anticipation and anxiety for both children and their families. Understanding what to expect at different stages can promote healthy development throughout adolescence and into early adulthood.
