Answer:
Nervous system
Explanation:
The nervous system in humans work together to collect information about the external environment because they consist of the brain, spinal cords and neurons. They collect information from external environment and those information travels through neurons from sense organs like eyes, ears, skin e.t.c as a form of electrical impulses. When they get to the end of the neuron, a chemical called neurotransmitters are released which travels across the cells and send it to the brain, the brain then process it and interprete the signals and respond to it as stimulus.
Answer:
Humus (hummus) is a dark organic matter in the soil which is produced by the decay of leaves or twigs (leaf litter). The litter is decayed in the soil by the action of microbial communities and chemcial reactions (together called as biogeochemical reactions). This process is also known as decomposition. The higher humus content in the soil makes it more fertile because there are more nutrients releasing due to increased turnover of the decomposing bacteria. Further, humus formation is increased if more water (moisture content) and oxygen is available.
Answer:
C. The role of photosynthesis in transferring carbon dioxide from the atmosphere to the biosphere
Explanation:
Photosynthesis is a process in which plants (and some other organisms whose cells possess chlorophyll) transform the energy they receive from sunlight, water, and carbon dioxide into carbohydrates they use as food and oxygen, which they release back into the atmosphere. This is shown in the diagram you were given (pictured below).
Since plants are a part of the biosphere and they take carbon dioxide from the atmosphere, we can conclude that the diagram shows the role of photosynthesis in transferring carbon dioxide from the atmosphere to the biosphere.
