The image above shows the natural progression of a forest in a process called ecological succession. If a mature climax forest i
liubo4ka [24]

Explanation:

The community may enter primary succession.

Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:

  • colonizing species exploiting uninhabited areas (Primary succession)
  • becoming a habitable and increasingly complex community
  • there is increased diversity of organisms (Secondary)

The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.

Like the harvested climax forest, secondary communities do not begin with the removal of soil and all biological life; other species, may be more suited to the altered conditions and begin to modify the area creating a new community.

However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

-Simple squamous epithelium

Explanation;

-Simple squamous epithelium is the single layer of thin, flat cells that line body surfaces which are not exposed substantially abrasive forces. The primary function of the columnar cell is that secretion and absorption simple squamous epithelium a single layer flat scale shaped cells.

-Simple squamous epithelium lines the air sacs, or alveoli, of the lungs. The alveoli are sites where air is exchanged in the lungs. Simple squamous epithelial cells in the alveoli allow oxygen from the air to enter the blood in the capillaries of the lung.

Blababa [14]

Answer:

A response is a _reaction to a stimulus. • A stimulus is anything that can cause an individual to respond or react. • Stimuli can be _internal or  external.

Explanation:

A  change in the cellular make up of an organisms due to response or reaction to a stimulus is called a response. This response can be due to a stimulus inside the  body , or due to effect of an external ( stimulus) object on the body-stepping on a sharp pin.

In either cases, the stimulus  is  receive by the receptors, which transfer the stimulus through the sensory neuron to the inter neuron in the CNS, for the motor neuron to bring an effective response at the effectors.
