The abiotic factors of a stream ecosystem involves salt, water, rocks, sediments and trash. This includes the temperature of the water, how much oxygen it contains, how acidic or basic it is, how fast or slowly, and how much sunlight penetrates the surface. A stream ecosystem is the ecosystem of a river viewed as a system operating in its natural environment, including biotic factors and abiotic factors.
The dam acts as a barrier between upstream and
downstream. Dams are also built for
irrigation, but it is also deliberately destroyed in favor of irrigated
farming. Though it provides freshwater, and makes people be protected by
droughts, but it can also damage the agricultural resources by limiting the
water in some areas.
Answer:
Mitochondria and the chloroplast
Explanation:
Electron transport refers to the transfer of of electrons from electron donors to electron acceptors via a reduction-oxidation reaction.
In the mitochondria the process is called Oxidative phosphorylation whereas in the Chloroplast it is called Photo-phosphorylation since it utilizes light.
Chemiosmotic mechanisms allow the movement of ions across a semi-permeable membrane down their electrochemical gradient.
In both mitochondria and chloroplast,have these mechanisms for the production of ATP .
Answer:
When the level of release of carbon dioxide during respiration and use of carbon dioxide during photosynthesis this results in a compensation point. At compensation point the net available carbon dioxide to phototrophs becomes zero. As, carbon dioxide is the chief ingredient for photosynthetic products like glucose and oxygen. These products are used up during the process of respiration. When the rates of two processes photosynthesis and respiration becomes equal. Phototrophic organisms will not be able to compensate for lack of carbon dioxide levels. Phototrophs will not be able to produce their food in the form of glucose and hence will not be able to respire too. This will result in lack of overall available food from phototrophs and lack of available oxygen for respiration. This will result in decline of organisms on earth.
The bones are: malleus (hammer-shaped) , incus (anvil-shaped) and stapes (stirrup-shaped).
They are together known as ear ossicles.
They transmit the vibrations from the eardrum or tympanum to the inner ear.
