Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting ...
Particularly common types of secondary succession include responses to natural disturbances such as fire, flood, and severe winds, and to human-caused disturbances such as logging and agriculture. In secondary succession, the soils and organisms need to be left unharmed so there is a way for the new material to rebuild. [9]
Success and succession happen in tandem in boreal forests. Primary succession, while part of the original landscape formation, is not vital like secondary succession. [10] Secondary succession consists of varied events: wildfires, flooding, mudslides and even excessive insect foraging act in this progression and cycle of boreal forests. [10]
The remainder is consumed by animals while still alive and enters the plant-based trophic system. After plants and animals die, the organic matter contained in them enters the detritus-based trophic system. [15] Ecosystem respiration is the sum of respiration by all living organisms (plants, animals, and decomposers) in the ecosystem. [16]
Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears. These animals have been endangered due to overhunting, an infestation of disease, loss of diet and habitat due to climate change, and human destructive activities, such as searches for natural gas and oil, mining, and road building.

In scientific ecology, climax community or climatic climax community is a historic term for a community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state. This equilibrium was thought to occur because the climax community is ...
For gap dynamics to occur in naturally disturbed areas, either primary or secondary succession must occur. Ecological secondary succession is much more common and pertains to the process of vegetation replacement after a natural disturbance. Secondary succession results in second-growth or secondary forest, which currently covers more of the ...
