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.

Which of the following ecological roles is/are played by at least some fungi? Select all that apply.A) AutotrophyB) PredationC)
Aneli [31]

The correct answers are:

B) Predation;

C) Decomposition;

The fungi are found in many different forms, and they practice numerous styles of life. The fungi can be considered as organisms that are decomposing. They are actually the main living organisms that take advantage of the decomposing organisms, but they too find themselves in a situation where they decompose once their life is over. Also, some fungi, around 150 species from what is known so far, are actually predators. They are feeding on nematode worms. They have developed ways to trap the worms, or just simply snag them with an adhesive that sticks to them.

The fungi though can not be considered as autotrophs. The reason for that is that they are not producers, but instead they use the producers as food source, thus making them heterotrophs.

An action potential in one segment of axon causes adjacent sections of axon membrane to reach threshold through what mechanism?
Furkat [3]
<h3>Answer:</h3>

The generation of local currents.

<h3>Explanation:</h3>

An action potential at the axon hillock generates local currents that depolarize nearby sections of axon to threshold. This change in membrane potential causes voltage-gated Na+ channels to open in the adjacent axon segment. This generates/regenerates the action potential in the adjacent segment, causing the action potential to propagate away from the axon hillock.

Explain the Three position of Meristematic tissues​
son4ous [18]
<h2>Answer:</h2>

There are three types of meristems on the basis of position, i.e

  1. Apical meristem.
  2. Lateral meristem.
  3. Intercalary meristem.
<h2>Explanation:</h2>

A meristem is the tissue present in  most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Generally differentiated cells(the cells other than meristems) do not divide and produce of a different type of cells.

Meristems are classified on the basis of their location in the plant:

  1. Apical meristem - these are the meristems located at root and shoot tips of the plant.
  2. Lateral meristem - these are the meristems located in the vascular and cork cambia in plants.
  3. Intercalary meristems - these are the meristems located at internodes, or stem regions between the places at which leaves attach, and leaf bases.

Result: There are 3 types of meristems.
