How does climate change affect soil fertility? Climate change can affect soil functions directly and indirectly. The direct effects include soil process changes in organic carbon transformations and nutrient cycling through altered moisture and T regimes in the soil or increased soil erosion rates due to an increased frequency of high‐intensity rainfall events.
How does climate affect soil? Climate: Temperature and moisture influence the speed of chemical reactions, which in turn help control how fast rocks weather and dead organisms decompose.

How does fertilization take place in plants?
From the anther the pollen grains are first deposited on the pistil’s surface, the stigma. There they germinate and form pollen tubes, which grow downward through the style toward the ovules. Fertilization occurs as a sperm cell in a pollen tube fuses with the egg cell of an ovule, resulting in a plant embryo.
Which fertilizer is best for flowers?
If you are looking to boost flower production, you want a mix like 15-30-15, which is high in flower-developing phosphorus. If you want to green up your lawn, choose a mix like 25-6-4, which is high in nitrogen. Many fertilizers are formulated for specific plants like roses, bulbs, or vegetables.

Why are men not fertile?
Male infertility can be caused by low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors may contribute to male infertility.
Does fertilization occur while the egg is in the follicle?
Ovulation is the time when an egg is released from the dominant follicle (winner of the race) within an ovary, into the fallopian tube where it can become fertilized by sperm. This is the only time during the menstrual cycle that a woman can become pregnant.

Losing topsoil to erosion contributes to a loss of inherent soil fertility levels of nitrogen, P, K, and thus to a decline in potential crop yield. The addition of manure and fertilizer can supply needed crop nutrients and help offset some loss of inherent fertility caused by soil erosion.
Do sharks use internal or external fertilization?
