Plants are the basis of nearly all ecosystems on Earth because they carry out the process of photosynthesis. Plants harvest ligh
Daniel [21]

Answer:

Trophic level

Consumer

Producer

Explanation:

All living organisms require energy for their life processes, which they obtain by taken in food. In an ecosystem, this food is derived when organisms feed on each other. This process that eventually leads to a flow of energy within organisms is called FOOD CHAIN.

A food chain or food web always begins with a unique set of organisms called PRODUCERS. Producers are autotrophs capable of harvesting light energy from the sun and use it to produce their food (chemical) in a process called PHOTOSYNTHESIS. Other organisms called HETEROTROPHS feed on these producers to derive energy. In ecology, they are called CONSUMERS. Other consumers feed on the previous ones also to get energy.

Hence, each step of the food chain is occupied by organisms that obtain and store energy by feeding on another organism. This step is called TROPHIC LEVEL.

In a nutshell, a PRODUCER (usually plants) starts the food chain/web due to its photosynthetic ability. This producer gets eaten by an organism called CONSUMER and in the process, the energy and nutrient stored in the producers flows to the consumer. Another consumers feeds on the previous one and the energy keeps flowing. Each step of the food chain occupied by an organism that stores and transfers this energy is called TROPHIC LEVEL.

(oxygen, electron transport chain, chemiosmosis, NADPH)
Vaselesa [24]

Hai there :3 I'm planning to study chemical engineering.

Question related to Biochemistry (Photosynthesis & Cellular Respiration)

1. Chemiosmosis.  In the process of chemiosmosis, specific enzymes (such as ATP synthase) create ATP. Hydrogen ions go from a higher proton concentration to a lower one, which is why it's called chemio"osmosis"

2. Electron Transport Chain (ETC). The name says it all. Simply explained, electrons are transported and transferred in the mitochondrial membrane.

3. Oxygen. O2, the diatomic molecule, is essential in respiration. In the final stage of respiration, at the near end of the electron transport chain, oxygen accepts protons to become water. Cells use O2 during oxidative phosphorylation.

4. NADPH. I remember learning what this acronym means by heart. Nicotinamide Adenine Dinucleotide Phosphate Hydrogen. NADPH is essential in photosynthesis as a typical coenzyme in the reduction of chemical reactions.

How many laws in biology ?????????/
Komok [63]

Answer:

Three Laws of Biology. “Social rules can be broken, but the laws of nature can't.”

A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms. Many of these regularities of ecology and biogeography are named after the biologists who first described them.
