Story: Blue green algae are a kind of bacteria found in many lakes. These organisms make their own food through photosynthesis.

Small animals including mayfly larvae eat the blue green algae Small fish such as yellow perch eat the mayfly larvae. The small fish provide food for larger fish such as walleye.
Question: Describe a model you could use to show the transfer of energy within the lake ecosystem. In your description make sure you include the position of each organism identified in the paragraph. Include the blue green algae, mayfly larvae, yellow perch, and the walleye.

Answer:

Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.

Many Proterozoic oil deposits are attributed to the activity of cyanobacteria. They are also important providers of nitrogen fertilizer in the cultivation of rice and beans. The cyanobacteria have also been tremendously important in shaping the course of evolution and ecological change throughout earth's history. The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras. Before that time, the atmosphere had a very different chemistry, unsuitable for life as we know it today.

The other great contribution of the cyanobacteria is the origin of plants. The chloroplast with which plants make food for themselves is actually a cyanobacterium living within the plant's cells. Sometime in the late Proterozoic, or in the early Cambrian, cyanobacteria began to take up residence within certain eukaryote cells, making food for the eukaryote host in return for a home. This event is known as endosymbiosis, and is also the origin of the eukaryotic mitochondrion.

Because they are photosynthetic and aquatic, cyanobacteria are often called "blue-green algae". This name is convenient for talking about organisms in the water that make their own food, but does not reflect any relationship between the cyanobacteria and other organisms called algae. Cyanobacteria are relatives of the bacteria, not eukaryotes, and it is only the chloroplast in eukaryotic algae to which the cyanobacteria are related.

Under which conditions do most types of cells function at optimal levels
Scrat [10]

Explanation:

Cells maintain a constant internal environment; this process called homeostasis, ensures that cells obtain an optimal environment in which they can best function.

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.

It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

For example, cells within the human body function at an optimal temperature between 97°F (36.1°C)  and 99°F (37.2°C). This is due to the optimal temperature requirement of the enzymes within the human body, which requires this specific range to obtain activation energy.
