A marine biologist discovers a new species of aquatic animal. Upon examination, it's determined that this animal lacks specialized respiratory organs like gills. How does this animal most likely obtain oxygen?
A marine biologist discovers a new species of aquatic animal. Upon examination, it's determined that this animal lacks specialized respiratory organs like gills. How does this animal most likely obtain oxygen?
- Through symbiotic algae living within its tissues.
- Through a complex system of internal lungs.
- By directly absorbing oxygen from the water through its skin. (correct)
- By consuming other organisms that have already extracted oxygen.

Study Notes
- Animals depend on natural processes and inner workings of their bodies to survive
- Animals have seven essential functions.
Seven Essential Functions:
- Feeding
- Respiration
- Circulation
- Excretion
- Response
- Movement
- Reproduction
Feeding:
- Evolution has produced different ways for animals to consume food
- Herbivores eat vegetation and plant life like leaves, roots, stems, flowers, and fruit
- Carnivores eat other animals
- Filter feeders strain tiny plants/animals from the water
- Detritivores consume decaying plants or animals
- Parasites live on/within a host organism and feed on it
Respiration:
- Animals consume oxygen and expel carbon dioxide.
- Most animals have developed complex respiration systems.
- Aquatic animals like fish use gills to extract oxygen from water
Circulation:
- Circulation is the movement and distribution of oxygen, nutrients, and wastes throughout an organism
Excretion:
- Excretion removes bodily waste from an animal's body
Response:
- The nervous system controls an animal's reflexes and behavior
Movement:
- Animals have muscles or muscle-like tissues that produce force when stimulated.
- Muscle contraction often works with a skeleton for support
Reproduction:
- Many animals reproduce sexually, where each parent contributes half of the offspring’s genetic blueprint
- Some invertebrates reproduce asexually
- Asexual parents produce offspring genetically identical to themselves
- Reproduction allows new offspring to inherit genetic tools to sustain life
