identify 3 abiotic factors and their roles in the economy in your own words
Answer:
Abiotic factors are the non-living parts of the environment that have a major influence
on living organisms. They can help determine things like how tall trees grow, where
animals and plants are found, and why birds migrate. The most important abiotic factors
include water, sunlight, oxygen, soil and temperature.
Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All
living organisms need water. In fact, water makes up at least 50% of almost all living
things. Some organisms are made up of 95% water! Water is also essential because
other substances easily dissolve into it. This allows water to carry nutrients to cells and
wastes away from them. Without water, animals become weak and confused, and they
can die if they don’t get enough water. Think of how you feel after you take a long run.
Do you feel thirsty? This is your body signaling to you that you need water.
Sunlight is the main source of energy on Earth, which makes it an extremely important
abiotic factor. Sunlight is necessary for photosynthesis, the process where plants use
carbon dioxide (CO2) and water to make sugar – food for the plants that later becomes
food for animals. Without the sun, plants could not live, and without plants, animals could
not live! Sunlight is also plays a role in the production of oxygen and to an area’s
temperature, which are discussed in detail below.
Like water, oxygen (O2) is another important abiotic factor for most living organisms.
Oxygen is used by cells as an energy source. It gives cells the energy they need to carry
out important functions, for growth, and reproduction. Without oxygen, humans and the
other organisms that use oxygen would not be able to live! Oxygen is produced by green
plants through the process of photosynthesis, and is therefore directly linked to sunlight.
Soil is considered an abiotic factor since it is mostly made up of small particles of rock
(sand and clay) mixed with decomposed plants and animals. Plants use their roots to get
water and nutrients from the soil. Soils are different from place to place – this can be a
big factor in which plants and animals live in a certain area.
Temperature is an abiotic factor that is strongly influenced by sunlight. Because the
amount and strength of sunlight varies by location, the earth’s surface has different
temperatures in different zones. While some animals and plants can bear extreme heat
or extreme cold, others can only survive well in moderate temperature ranges. In fact, all
plants and animals are adapted to survive between a minimum and maximum range of
temperatures. For example, a penguin from the polar region couldn’t live in a 110°F
desert. It would be too hot! Temperature, then, helps to influence which plants and
animals can live in an area.

If the potential difference across a 30.0-ohm resistor is 10.0 volts, what is the current through the resistor?
O A 0.25 A
OB 3.0 A
OC 0.33 A
OD. 0.50 A
Answer:
C 0.33 A
Explanation:
The current through the resistor can be calculated using the formula;
V = IR
Where; V = Voltage (volts)
I = Current (Ampere)
R = Resistance (Ohms)
According to this question, I = ?, V = 10.0volts, R = 30.0ohms
V = IR
I = V/R
I = 10/30
I = 0.33A
Hence, the current through the resistor is 0.33A

ATP can convert to ADP during ___________.
Answer:
phosphorylation
Explanation:
ATP usually releases energy by breaking down the weak phosphate cell present. The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.
Answer:
phosphorylation

Primary productivity
B
Gross primary productivity
С
Net primary productivity
D
Cellular respiration
Answer:
C. Net Primary productivity
Explanation:
In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.
The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R
Where, R = energy lost via respiration.
what are limiting factors in the tundra
Answer:
the lack of vcegitation
Explanation:
Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?
Answer:
Oxygen cycles keeps the flow of oxygen at a constant rate.
Explanation:
The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.
Answer:
A.) The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.
