The correct answer is option (A) The snake population will decrease rapidly and the grass population will increase rapidly.
A food chain can be defined as a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. Each level of the food chain is called the trophic level. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.
In the terrestrial food chain given above, grass → rabbit → snake → Hawk, the decrease in the any population will effect the other organism at a different trophic level of the food chain. A sudden decrease in the population of rabbits due to trapping will rapidly decrease the snake population due to scarcity of food and the grass population will increase rapidly due to the lack of the consumers which are the rabbits.
Answer:
The correct answer is There are very few receptors on the soles of a person's feet.
Explanation:
The skin is made up of a layer called the epidermis. The epidermis contains cells that are very sensitive and are responsible for perceiving everything we touch by sending this information to the brain.
All the nerve endings that our body has are in charge of controlling the sense of touch.
All the sensations that we perceive when touching something with any part of the body are linked to the sense of touch.
The most sensitive places on our body are palms, lips, tongue, soles of the feet, fingertips, eyelids and face.
Therefore the correct answer is There are very few receptors on the soles of a person's feet.

Answer:
The ability of species of living beings to overproduce offspring
Explanation:
Darwin proposed that species have the ability to produce offspring at a rate that could cause a geometric increase in the population size. This is called biotic potential. The overproduction of offspring causes intraspecific competition for the limited available resources. Darwin reasoned that the overproduction of progeny leads to a struggle for existence between the individuals of a population. He observed that the struggle for existence does not allow the population size of species to grow geometrically.
1. Burning of fossil fuels.
Under natural conditions the release of carbon from fossil fuels
occurs slowly, as they are sub ducted into the mantle, and CO2 is released
through volcanic activity. However, humans are heavily reliant on fossil fuels,
and extract it from the lithosphere in great quantities. Put in to fire a coal,
oil, natural gas, and other fossil fuels – for industrial movement and power
generation for example, neglect the carbon from the fossil fuels and emits it
as CO2 into the atmosphere.
2.
Land use and land cover change (e.g. deforestation)
Big
part of carbon are stored in living plants. Then, land use changes, most importantly
the clearance of forests (which are very densely inhabited by plants, and
therefore contain a large amount of carbon), can influence the carbon cycle in
two ways. Firstly, removing of vegetation will let the plants die which would
otherwise be capturing carbon from the atmosphere through photosynthesis. And
as dense forests are change by crops/pasture land/built environments, there is
usually a net decrease in the carbon store, as smaller plants (and worse still,
concrete) store far less carbon than large trees. Deforestation also make much
more soil to be eroded, and carbon stored in the soil is rapidly taken into
rivers.
<span>Because the nature is in cycle of the carbon cycle, humans are
affected and cause the lead to a number of amplifications and feedbacks. Thereby
releasing more CO2 to the atmosphere. Increases in global temperature also
affect ocean temperatures, modifying oceanic ecosystems and having the
potential to disrupt the oceanic carbon cycle, limiting the ocean’s capability to
absorb and store carbon.</span>
