Answer:
A physical environment with different species that interact with one another and with nonliving things is called an ecosystem.
Ecosystem is the functional unit of nature. An ecosystem can be different in size according to the communities living in that ecosystem. Abiotic and biotic components together make an ecosystem.
Chemical and physical factors come under abiotic components. Physical components like water, air, light, temperature have more effects on the ecosystem than chemical factor.
Organisms are the biotic component of an ecosystem. They can be autotrophs or heterotrophs. Many organisms make a population, many populations combine to form community and many communities combine to form an ecosystem.

Answer:
The correct answer will be- the molecules move from high concentration to low concentration.
Explanation:
Diffusion represents the movement of solute particles that is ions or molecules. The movement is driven by the concentration gradient that is from the higher concentration to lower concentration.
The diffusion can be categorized into two types: simple and facilitated diffusion. In biology, diffusion plays an important role as the important solute particles move into and out of the cell through this process.
Thus, the molecules move from high concentration to low concentration is the correct answer.
During diffusion, molecules move from area of high concentration to an area of low concentration to achieve equilibrium.
During diffusion, molecules move from an area of high concentration to an area of low concentration. This happens due to the random motion of the molecules. The goal of diffusion is to achieve equilibrium, where the concentration is equal throughout the space.

Answer:
Prokaryotes are the most primitive form of life that exist on earth. They came before eukaryotes.
The main difference is the presence of nucleus which is present in eukaryotes and absent in prokaryotes.
The genetic material of prokaryotes are dissolved in the cytoplasm whereas in case of eukaryotes the genetic material is in-tacked inside a double membrane organelle nucleus.
There are many more membrane bound cell organelles found in eukaryotes that are absent in prokaryotes.
