The right answer is Lichen.
In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.
Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .
im not sure but i think the answer is If there is no oxygen present, then the cell does either alcohol or lactic acid fermentation. If oxygen is present, the citric acid cycle follows glycolysis, with oxidative phosphorylation following the citric acid cycle.
-I cant see teh image,,, if you include it i could answer! (:
A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon- containing chemical compound for an indefinite period.
Answer: The correct answer is- E) structural framework.
Fibrous proteins are water insoluble, elongated filamentous like structures that that provide structural framework ( they have special types of helices in their structures) to the cells or tissues of organisms.
They contain repetitive amino acid sequences in their structure that provides strength to the structure.
They are very less sensitive to any change in pH, temperature, as well as enzymatic digestion.
They are usually involved in the formation of connective tissue.
Example of fibrous protein- Actin, myosin, elastin, keratin.
There are 24 spiders per square meter.
The largest population that an ecosystem is able to support indefinitely with the resources that it possesses is referred to as the "maximum load" by population biologists. This number is referred to as the carrying capacity of the ecosystem. The carrying capacity of an ecosystem is determined by a wide variety of biotic and abiotic factors.
The population density is calculated by the formulae :
Population density = Number of people / Total area occupied
Given in the question,
Number of people = 12,600
Total area = 525 sq. meter
Therefore, population density = 12600/525
= 24
Therefore, the number of spiders found per square meter is 24.
