Sir Isaac Newton PRS was an English mathematician, physicist, astronomer, theologian, and author from the late 1600s
Trophic Levels in a food chain
Autotroph (producer): An organism that produces its own food using sunlight or chemical energy
Heterotroph (consumer): An organism that consumes another organism for food
Food chain: A series of organisms in which energy is transferred to another
Food web: A network of feeding interactions, usually consisting of multiple food chains
Trophic level: Each step in a food chain or food web
Biomass: The total amount of living tissue within a trophic level
Biomass and energy transfer:
When energy enters a trophic level, some of it is stored as biomass (as part of organisms' bodies). This is the energy that's available to the next trophic level, since only energy storied as biomass can get eaten.
As a rule of thumb, only about 10\%10%10, percent of the energy that's stored as biomass in one trophic level (per unit time) ends up stored as biomass in the next trophic level (per the same unit time). -- Khan Academy
it starts with Photosynthesis
Photosynthesis is the chemical reaction through which sunlight is transformed into sugar to use as:
1). Usable energy to power cellular functions
2). Stored energy that is kept in oils as potential energy and
3). Some energy is used as building blocks for cell structures.
The molecule that cells use to power energy requiring functions is called ATP.
What is in food?
Food is a source of macronutrients: carbohydrates, proteins, and fats
Essential nutrients: substances that cannot be synthesized by the body and need to be consumed, pre-assembled through the diet, this includes certain amino acids and fatty acids, vitamins, and minerals.
Essential amino acids: there are eight amino acids that the body cannot synthesize and needs to get from food
