Answer:

A.  passive transport by diffusion

Explanation:

Diffusion and osmosis are both types of passive transport. They do not require energy. Diffusion is the general term for the process. Osmosis is the diffusion of water molecules.

Many small, uncharged molecules can cross the cell membrane by diffusion. Oxygen and carbon dioxide are examples of two small molecules that pass the cell membrane by passive transport.

Larger or charged molecules require energy to cross the cell membrane. This is achieved by active transport.

leva [86]

Answer:

Each is a mini-ecosystems and a representation of much larger ecosystems found on earth. The mini ecosystem is the terrarium

Explanation:

A terrarium is the accumulation of small plants that are being grown in the transparent, or sealed container. It is a closed environment type and are mostly used to know how the ecosystem works within itself. Inside that small container, we can observe various natural processes like photosynthesis, respiration, as well as water cycle. Some small plants cannot adapt well in the home environment, so they can be grown in the terrarium. If they are properly planted and taken care of they can grow with minimum care. By this we can grow indoor plants with less care.
