Nutrients and Energy Transfer

A nutrient is a substance that provides nourishment essential for an organism's growth, maintenance, and survival.
Algae and plants play a primary role in the food chain as producers, converting sunlight into chemical energy through photosynthesis.
The law of conservation of mass states that matter cannot be created or destroyed, only transformed or converted from one substance to another.

Energy Transfer and Nutrient Cycling

Nutrients are essential for organisms to function, providing the necessary building blocks for growth, development, and maintenance.
The inefficiency in energy transfer at higher levels of the food web is attributed to the loss of energy as heat, a result of the second law of thermodynamics.
As matter and energy move through an ecosystem, they are transformed and transferred from one level to the next, with some energy being lost as heat.

Key Roles and Processes

Algae and plants are the primary producers of the food chain, providing the nutrients needed for organisms to function.
The law of conservation of mass ensures that matter is cycled and recycled within an ecosystem, with nutrients being reused and transformed.
Energy is transferred from one level to the next in the food web, with some energy being lost as heat, resulting in a decrease in available energy at higher levels.
