Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. The boundaries of an individual abiotic factor can be just as unclear as the boundaries of an ecosystem.These are often referred to as abiotic factors. Abiotic factors are non-living elements found within an ecosystem. There are six abiotic factors that affect plant growth: air, water, space, temperature, light and soil (nutrients).The two most important abiotic factors affecting plant primary productivity in an ecosystem are temperature and moisture.
LEARNING OBJECTIVE[ edit ]
Identify the abiotic factors that affect plant growth
KEY POINTS[ edit ]
Primary production, on which almost all of life on earth is dependent, occurs through either photosynthesis or chemosynthesis.
Annual biomass production, used to estimate net primary productivity by plants in an area, is directly influenced by an environment's abiotic factors, which include temperature and moisture.
Warm and wet climates have the greatest amount of plant biomass because they offer conditions in which photosynthesis, plant growth, and the resulting net primary productivity are highest.
TERMS[ edit ]
biomass
the total mass of all living things within a specific area, habitat, etc.
eco-region
a region, smaller than an ecozone, that contains a distinct biodiversity of flora and fauna
chemosynthesis
the production of carbohydrates and other compounds using the oxidation of chemical nutrients as a source of energy rather than sunlight; it is limited to certain bacteria and fungi

The ability to work with the sick and the infirm depends on one's ability and willingness to show Empathy.
Option A is correct .
What is empathy ?
Empathy, the ability to understand and share the feelings of another, is an important asset to improve health outcomes for patients with LHL. Empathy is much more than just knowing a patient’s medical history, symptoms, or signs of disease and goes far beyond clinical diagnosis and treatment. It is the ability to truly understand the patients’ emotions, fears, pain and worry and the ability to respond to these.
The term “empathy” is used to describe a wide range of experiences. Emotion researchers generally define empathy as the ability to sense other people's emotions, coupled with the ability to imagine what someone else might be thinking or feeling.

Explanation:
Answer:similar meiosis cell division in oogenesis and spermagenesis.
Explanation: gametogenesis is the production of gamete through meiosis.
In the production of egg,the primordial germ cell forms the oogonia.the oogonia grows into the primary oocyte.the primary oocyte undergoes the first meiosis to give secondary oocyte and a polar body.
The secondary oocyte undergoes the second meiosis the ovum and a second polar body.
In spermatogenesis,the primodial germ cells forms the spermatogonia,which grows into the primary spermatocyte.the primary spermatocyte undergoes the first meiosis to form two secondary spermatocyte .the secondary spermatocyte undergoes the second meiosis to form spermatids,which differentiates into spermatozoa.
Both meiosis division results in haploid male and female gametes.
A functional sperm has a head containing nuclear materials and acrosome for penetrating the egg layers .there is also a midsection that has mitochondria for the production of ATP.the sperm uses it's flagella to swim towards the egg.
A functional egg has a diameter of 0.1mm.it has cortical granules and yolk for nutrition.
It has two membranes;the plasma membrane and the vitelline membrane.
