How does decomposers help the soil?

How is Nitrogen made available to organisms from the soil? Bacteria in the soil and roots of plants recycle N2, making it available to other organisms.
How do you keep soil fertile? Decomposers help plants by breaking down organic matter, or matter that was once alive, and releasing nutrients back into the soil.

Why are frozen eggs not fertilizing during icsi?
When eggs are frozen, thawed and subjected to the extreme freezing temperatures, they will have a hardened zona which will not permit successful fertilization. Without ICSI, the fertilization rates of these frozen oocytes will be very low.
What does fertility rate measure?
This entry focuses on the number of births per woman in a population. The most commonly used metric is the Total Fertility Rate (TFR) – or often simply ‘fertility rate’ – which measures the average number of children per woman. The global average fertility rate is just below 2.5 children per woman today.
What fertilizer to use for raspberries?
Raspberry plant fertilizer should be heavy in nitrogen, although a balanced type is often preferred. For instance, the best fertilizer for raspberry bushes is a 10-10-10 fertilizer or actual nitrogen at a rate of 4 to 5 pounds (1.8 to 2.3 kg.) per 100 feet (30.4 m.) of row.

(1) day-3 follicle stimulating hormone (FSH), (2) anti-Mullerian hormone (AMH), and (3) antral follicle count (AFC). The number of antral follicles and the total ovarian volume as measured by transvaginal USG have been mentioned in the literature to predict declining fertility related to reproductive aging.
Can you get pregnant outside of fertility window?
It’s possible to get pregnant outside of your predicted fertile window because timing of ovulation may differ each month and sperm lives in the body for several days. Therefore, though more unlikely at some points, pregnancy can result from unprotected sex at any time during your menstrual cycle.
How does in vitro fertilization take place?
During in vitro fertilization, eggs are removed from mature follicles within an ovary (A). An egg is fertilized by injecting a single sperm into the egg or mixing the egg with sperm in a petri dish (B). The fertilized egg (embryo) is transferred into the uterus (C).
