1 : How do you calculate the adjusted amount of energy that is available to organisms that are one trophic level above producers? 2 : Methylmercury biomagnifies in an ecosystem, meaning its concentration as it moves through each higher trophic level

3 : Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?

4 : Energy transfer is inefficient between trophic levels because

5 : Primary productivity is defined as

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
