Explanation:
1. the similarity between biosphere and ecosystem is that they both have organisms that depend on each other and the difference is that biosphere uses every single organism while ecosystem only uses organisms that are inside of the ecosystem. 2. the similarity between theory and hypotheses is that they are both something that have to be scientifically proven and the difference is a theory relies on evidence and a hypothesis relies on a possibility. 3. a similarity between independent variable and constant is that they both change at the same time and the difference is that an independent variable is controlled or changed by the scientist while a controlled variable is one that they want to remain the same.
Answer:
In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
Explanation:
<em>Unknown source.</em>
It's called the cell membrane, it can control what substance can go in and out of cell.
The relationship among births, deaths, and carrying capacity in equilibrium species is that the equilibrium species have a low birth rate and a low death rate and tend to stay near the carrying capacity. The carrying capacity is the population size of the species that the environment can sustain indefinitely, given the food, habitat, water and the other necessities available in the environment. It determines the equilibrium species, together with the death rate and the birth rates of a given species in an ecosystem.
