  • Soil becomes enriched during soil formation by decaying organisms.
  • As the organisms decay in the soil due to the action of several decomposers, their nutrients are released into the soil.
  • These nutrients that are released into the soil are responsible for making the soil enriched with nutrients.
  • The decomposers such as the bacteria and fungi play a very important role in the soil enrichment as without them the decaying organisms would not be further broken down and no nutrients could be extracted from them.

Succession occurs when environmental factors affecting an ecosystem change. True or False
zhannawk [14.2K]

Answer: True

Succession is the phenomena in which changes in the biotic and abiotic factors of the environment leads to change in the ecosystem. A succession is a process in which a biological community is replaced by another biological community until a mature ecosystem is formed this process is influence by environmental factors. Primary succession is the primitive environment where no biotic community previously existed it is followed by secondary and subsequent succession were life forms develop and form an ecosystem. Some of the environmental factors are:

Topographical : These are the change in the region or habitat were succession occurs. Landslides, volcanic eruption, glacier melting etc. are the examples , as these topographical changes can bring reformation of the landscape. The disturbance caused by these topographical changes will allow the disturbance tolerant species to repopulate the habitat.  This can be a transition from primary to secondary succession.

Soil : It is an abiotic factor.The growth of the plants requires suitable soil conditions. The type of soil will affect which species will inhabit the area. The soil moisture and pH greatly affect the number of plant species in an area.

Climate : It can influence the direction of succession. Climatic factors includes rain, wind etc. For example a region lacking proper rainfall the species will be tolerant to dry and drought conditions. The region with heavy rainfall, the species will be more tolerant to moisture. Wind being a climatic factor can cause wind erosion affect the soil quality. Wind can lead to heavy forest fires can therefore, wiped out community.

Which division of the diencephalon acts as an information filter for sensory information that is forwarded to the cerebrum?
muminat
<h2>The Thalamus.</h2>

Explanation:

Dencephalon is the part of the forebrain and includes three parts- epithalamus,thalamus and the hypothalamus.

Epithalamus is a non-nervous part , it remains fused with pia mater and forms the anterior choroid plexus.

The thalamus  is located between the midbrain and the cerebral cortex. It filters sensory information and directs them to appropriate parts of cerebrum.

Hypothalamus is located beneath the thalamus. It is an integrating center for many important homeostatic functions.
