Answer: What stage of succession is taking place in the forest?
The first stage of forest succession is the grass, or plant stage, which occurs after land has been cleared due to natural events or otherwise. The sudden clearing floods the ground with sunlight; very shade-intolerant pioneer species like longleaf pine, aspen, or cottonwood begin to compete with grasses.
What three major processes contribute to succession?
Causes of succession
Three major causes have been identified for the process of succession. a. Initiating causes - These include biotic and climatic factors which destroy the existing populations of the area. Climatic factors include wind, fire, natural disasters, erosionWhat are the 4 stages of succession?
There are five main elements to ecological succession: primary succession, secondary succession, pioneer and niche species, climax communities and sub-climax communities.

Lipids differ from other large biological molecules in that they are not truly polymers ; Lipids are not all made of the same type of monomer. Their association as a group is related to their behavior rather than their structure.
Cell division is characterized by two important processes called the karyokinesis followed by the cytokinesis. Karyokinesis refers to the division of the nucleus which is followed by the division of the cytoplasm called the cytokinesis. In animal cells, it is by the formation of a cleavage furrow and in plant cells it is by the formation of a cell plate. Cytokinesis results in the formation of two daughter cells. If the cells are treated with chemicals that block cytokinesis, the seperation of cells is not possible leading to the formation of abnormally large sized cells, each containing two nuclei or sometimes can be multinucleated.
The answer is a process that selects variation that help survival and that spreads the variation to more offsprings.
The idea is that there is a higher chance of survival if the organisms has certain characteristics and it is more likely to pass on their genes of this characteristic to the next generations.
For example, there's dark colored fish and white fish. In the deep ocean, dark colored fish can camouflage themselves. However, white fish can be seen easily by predators. Therefore, eventually more dark colored fish survives and more offsprings are dark ones.
A. Photosynthesis to generate energy
