The missing part of the question is -
" Is this Primary or Secondary Succession?"
Answer:
The correct answer is - secondary succession.
Explanation:
Recolonization of the plant and animals to habitat after a major disturbance such as flood, lava eruption, wildfire, or human disturbance is characterized as secondary succession.
In this particular case, there is secondary succession occurs, there is man-made disturbance tajes place as logging company clear the spruce trees from a habitat, and after clearing the land the spruce seedlings began to sprout, birds, rabbits recolonize to the area.
The correct answer is option A, It grows healthy crops.
Because the loess soil is very fertile due to its ability to exchange cations and porosity.
Due to cation exchange capacity the plants easily absorbs nutrients from the soil and due to porosity the soil holds the water, oxygen and nutrients which is absorbed by the roots of the plants for their nourishment.
Answer:
Option A, Start the reaction by absorbing light energy
Explanation:
Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.
Hence, option A is correct.
Answer:
Calcitonin
Explanation:
Calcitonin hormone is released by the para follicular cells of the thyroid gland. This hormone works against the parathyroid hormone.
Calcitonin hormone regulates the level of calcium by decreasing the blood calcium level. This hormone inhibits the osteoclast activity of the cells and decreases the absorption of calcium in pregnant women and child. Hence, calacitonin decreases plasma calcium levels in pregnant women and children.
Thus, the correct answer is option (B).
