Phytoplankton - zooplankton- small fish -mammal
This is the food chain of the organisms.
From phytoplankton,which are microorganism, they are eaten by zooplankton. Zooplankton are heterotrophic planktons such as jellyfish and forams. Next to this is small fish, they eat those zooplankton. Lastly, the mammals will eat those fish.
Acids have a ph of 6 and below whole bases have a ph of 8 and above. If a human has to much acid in their stomach they can take a pill that will lower it back to its normal ph level
All forms of farming have major impacts on biodiversity, especially when new land is brought into cultivation. Habitats are destroyed and new ecological niches created which allow typical farmland species of birds, insects, mammals and weeds to establish themselves.
The best estimate of the population of trout in the lake is 500 individuals.
The low number of tagged trout recaptured may be because the tags slipped off.
This possibility can be reduced if the student used tags that does not slip off easily.
<h3>Mark and recapture method</h3>
The formula for calculating the estimated number of individuals in the population is given as:
where:
- N = estimated Number of individuals in the population
- M = number of individuals captured and Marked
- C = total number Captured the second time (with and without a mark)
- R= number of individuals Recaptured (those with a mark)
Calculating the estimate trout population:
N = (50*40)/4
N = 50
Therefore, the best estimate of the population of trout in the lake is 500 individuals.
The low number of tagged trout recaptured may be because the tags slipped off.
This possibility can be reduced if the student used tags that does not slip off easily.
