Answer:
Diffusion
Explanation:
Diffusion has a membrane which allows even large molecules to pass through it whereas osmosis allows only water molecules as it has a partially permeable membrane.
Not sure what you mean but here's what i think
1.They are substrate-specific, because it's a lock-and-key mechanism.
2. They are re-used
3. They can catalyze reactions
4. They decrease activation energy
5. They are proteins by nature.
1.limiting factor is a variable of a system that, causes a noticeable change in output or another measure of a type of system
2. Examples of limiting factors include competition, parasitism, predation, disease, abnormal weather patterns, natural calamities, seasonal cycles and human activities. In terms of population growth, limiting factors can be classified into density-dependent factors and density-independent factors.
3. When organisms face limiting factors, they show logistic growth.Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity
All the organisms that eat the middle organisms will die and the organisms that get eaten by the middle organisms will flourish.
