They help with storing "food" in fruits and foods to make them edible for us people.
Answer:
The correct answer will be option-C.
Explanation:
The survivorship curves are the representation of the proportion of individuals of the given species which are alive at different ages in the population of species. The curves are represented in the form of a graph with the number of individuals plotted on the y-axis to the age of survivorship on the x-axis.
The survivorship curves are of three types: Type I, II and III out of which type three represents the population with equal probability of dying at all age groups. This is represented by a straight line on the graph.
Thus, Option-c is the correct answer.
Answer:
translucent
Explanation:
opaque surfaces allow no light to pass through, transparent surfaces allow all light to pass through and reflective surfaces reflect light.
Answer:
Our atmosphere (air) is comprised of 78% of nitrogen. However, this nitrogen is in its elementary state (N₂) and therefore is quite inactive, so the plants can not use it directly. Changing the elementary nitrogen into more reactive forms (NH₃, NO₂, HNO₃) is occurring through the process called nitrogen fixation. It is happening via two processes.
First one is physical nitrogen fixation. When some type of atmospheric physical energy (lightning bolt, for example) reacts with N₂, it splits it in two very reactive N atoms, enabling them to react with oxygen in order to form NO₂.
Second process is biological nitrogen fixation. It's done by bacteria, special bacteria living in the soil, able to use elementary nitrogen for its metabolical pathways resulting in production of ammonia, which can be used by plants. It's noteworthy that bacteria are responsible for about 90% of all nitrogen fixation.
Because some energy is lost as heat,sound etc
