Atmosphere: Plants on land  release oxygen  during photosynthesis.

Geosphere: Bacteria living  underground convert  ammonia to nitrates.   The waste from  livestock adds  nitrogen to the soil.

Hydrosphere: Marine life adds  carbon dioxide to  ocean water during  respiration

Explanation:

Living beings including animals, plants, and bacteria are part of the biosphere of Earth; additionally, these interact with other systems of Earth such as the atmosphere, geosphere,  or hydrosphere. In the case of the atmosphere, which refers to the gases above the surface of Earth, this has an interaction with living beings due to the exchange of gases between both systems. An example of this is plants because they take carbon dioxide from the atmosphere and release oxygen as part of photosynthesis.

On the other hand, the geosphere comprises soil, rocks, minerals, and in general, all that composes the solid non-living parts of Earth. Additionally, there is an interaction between the geosphere and biosphere can occur due to the exchange of substances as it occurs in the case of bacteria converting ammonia to nitrates or in the case of livestock releasing nitrogen.

Finally, the hydrosphere includes all bodies of water such as rivers, oceans, or lakes. Also, there is an interaction between this and living organisms through the exchange of substances, which includes marine life adding carbon dioxide to oceans.

transmission electron microscopes and scanning electron microscope

Explanation:

Microscopes are equipments used to amplify view of very minute specimens that cannot be seen with the naked eye. However, as stated in this question, different microscopes are used by scientists for various purposes. These microscopes include: compound microscope, transmission electron microscope, dissection microscope, scanning electron microscope etc.

- Dissection microscope and compound microscope are both types of light microscope that uses light source to view specimens. They both can be used to view life specimens.

- Contrarily, transmission electron microscopes and scanning electron microscope are both electron microscopes that uses beam of electrons to capture the image of a specimen. Specimens to be viewed under electron microscope are placed in a VACUUM, which causes the cells of the specimen to die.

Hence, transmission electron microscopes and scanning electron microscope can only view dead/non-living specimens.

Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.

In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.

Competition leads to differential survival and reproductive success among individuals.

Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.

These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.

Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.

Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.

Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

Answer: I think it’s is sunlight I hope this is right

Explanation:

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.Plants use chlorophyll, usually found in their leaves, to absorb sunlight. The light energy from the sun is what fuels the reactions that transform carbon dioxide and water into glucose and oxygen. Without light, photosynthesis is impossible

In the process of sexual reproduction, mating of male gamete and female gamete is required for the fertilization to take place in humans.

A gamete is an animal or plant reproductive cell. Male gametes in animals are known as sperm, while female gametes are known as ova or egg cells.

Fertilization is the process in which a woman's egg combines with a man's sperm to form an embryo.

Usually, the fallopian tube that connects an ovary to the uterus is where fertilization occurs. An embryo begins to develop if the fertilized egg successfully passes through the fallopian tube and implants in the uterus.
