Answer:
The correct answer is "The ammonia is controlled with a filter that uses two type of bacteria."
Explanation:
- The Biosphere on earth is composed of all the ecosystems, while each ecosystem is composed of the abiotic and biotic components and their mutual interactions. Aquarium is an example of aquatic ecosystem.
- Abiotic components constitute the non-living part of the ecosystem.
- Biotic components constitute the living part of the ecosystem.
- In the aquarium,
- The abiotic components include the air, water, heat, minerals, sunlight, fluorescent light.
- The biotic components include the aquatic plants, aquatic animals and the bacteria (in the filter attached to the aquarium).
- These bacteria are responsible for fixing dissolved nitrogen gas present in the water of the aquarium to ammonium and are called nitrogen-fixing bacteria.
- Free living bacteria like cyanobacteria or blue-green algae are examples of nitrogen-fixing bacteria.
- Fixation of dissolved nitrogen gas to ammonium and then conversion of ammonium to nitrites and nitrates (done by other bacteria) is essential because plants (terrestrial or aquatic) can use only nitrates as the source of nitrogen for the purpose of metabolism.
Regulates body temperature (sweating, shivering), blood pressure, pH levels, and glucose (sugar) levels
Answer:
It will overpopulate and harm
Explanation: without a predator the frog will most likely hurt the native animals and plants which isn’t good for the environment.
Answer/Explanation:
In eukaryotes, photosynthesis occurs mainly in green plants. These organisms have specialized organelles called chloroplasts that carry out photosynthesis. These contain photoreceptors that absorb photons from the sun through a pigment called chlorophyll, providing the energy to synthesise glucose from carbon dioxide and water.
In contrast, prokaryotes that carry out photosynthesis are able to do so because they have folds in the plasma membrane that permit the attachment of chlorophyll. They do not have specialized membrane-bound organelles like eukaryotes.
