Answer:
Marine ecosystem have biotic organisms like phytoplankton and photosynthetic algae that do photosynthesis and converts the atmospheric carbon dioxide into organic matter most of the carbon dioxide is released when other organisms eat phytoplankton and release the carbon dioxide through respiration.
But some of the algae and phytoplanktons die naturally get down to the bottom of the ocean where they make carbon sink. Some organisms accumulate CO₂ in their exoskeleton that is made up of calcium carbonate.
Therefore this use of carbon by living organisms in oceans brings carbon dioxide from the atmosphere to oceans. This is why the ocean plays a critical role in the carbon cycle and called carbon sink.
1) the manipulative variable is the salt
2) the responding variable is how many purple eggs hatched
3) beaker A was the controlling variable
Answer:
Carrying capacity can be described as the maximum number of population of a species that a particular habitat can hold.
There are a number of events which effect the carrying capacity like:
Environmental changes like weather conditions might become favorable for a species in a habitat. It might be that a certain weather condition raises more food for a species. Hence, the carrying capacity would increase.
It might be conditions like drought make the availability of nutrients scarce for a population of species. In this case, the carrying capacity of the ecosystem would decrease.
It might happen that other species might come to live in the particular area. That species will deplete the availability of resources and cause the carrying capacity to decrease.
If adequate amount of rain fall occurs in an area, it might cause the carrying capacity of a species to increase as there will be more water. But if the water supply becomes scarce, the carrying capacity would decrease.
