Nutrient CycleDaniel Vega

Humberto Escoto

In biology, the nutrient cycle is a concept that describes how nutrients move from the physical environment into living organisms, and subsequently are recycled back to the physical environment.

What is the Nutrient Cycle?

Micronutrients are nutrients required by humans and other organisms throughout life in small quantities.

What are micronutrients?

Macronutrients are nutrients required by humans and other organisms throughout life but in big quantities.

Macronutrients

A limiting factor or limiting resource is a factor that controls a process, such as organism growth or species population, size, or distribution.

What is a limiting nutrient?

Carnivores

Herbivores

Plants

Nutrients

This term, is based on the bottom-top model.

How does nutrient availability relate to the primary productivity of an ecosystem?

Carbon is not a nutrients for plants all carbon use by plants to form sugar, stratches, cellulouse, etc.

Why isnt carbon added to plant fertilizers?

nitrogen is the main limiting nutrient in saltwater environments.

Which is the typical seawater limiting nutrient?

The typical limiting nutrient is Phosphorus(P).

Which is the typical freshwater limiting nutrient?

Fertilizer contains nutrients that help crops grow, but not all of the nutrients (like nitrogen and phosphorus) are used by the crops. The ground water collects these leftover nutrients and carries them into large water bodies, these ecosystems have a natural equilibrium.

How is fertilizer runoff related to algal bloom?

Lake Water-Quality Classification

(of a lake or pond) having low levels of nutrients and high levels of dissolved oxygen.

What do Oligotrophic mean?

Mesotrophic is a body of water,having a moderate amount of dissolved nutrients.

Whats does Mesotrophic mean?

It is a process when a body of water gets an abundant supply of nutrients by excessive organic matters, sewage, or fertilizers and consequently stimulates huge algal growth.

Whats does Eutrophic mean?

The quantities of nitrogen, phosphorus, and other biologically useful nutrients are the primary determinants of a lake's trophic state.

Whats does Hypereutrophic mean?
