Nutrition, Digestion, Absorption, and Nitrogen Excretion

Nutrition, Digestion, Absorption, and Nitrogen Excretion Adaptations for Feeding Heterotrophic organisms can be classified by how they acquire their nutrition. Decomposers , mostly protists and fungi, absorb nutrients from dead organic matter.

Osmoregulation and Excretion

Osmoregulation and Excretion. Darian Hands Lisa Fan Victoria Donelan TJ Kellogg. Osmoregulation. Osmoregulation is how animals regulate solute concentrations and balance the gain and loss of water Excretion is how animals get rid of the nitrogen-containing waste products of metabolism.

The Human Excretory System

The Human Excretory System. Biology 2201 Unit 3 Section 4. Excretory System. The kidneys regulate the amount of water, salts and other substances in the blood. The kidneys are fist-sized, bean shaped structures that remove nitrogenous wastes (urine) and excess salts from the blood.

1. Because I live in water, I excrete urea, a water soluble nitrogenous waste.

Which of these animals correctly describe how its nitrogenous waste is related to its phylogeny and habitat?. 1. Because I live in water, I excrete urea, a water soluble nitrogenous waste. 3. Living on land, I need to conserve as much water as possible, so I excrete a solid nitrogenous waste.
