Week 12 UNE BIOL 1011: Final Exam
Questions and Correct Answers.
List the five categories of organic nutrients. - Answer Carbohydrates
Proteins
Lipids
Nucleic acids
Vitamins
Carbohydrates - Answer Primary source of energy for cells.
Proteins - Answer Build and repair tissues, enzymes, hormones, immune function.
Lipids - Answer Long-term energy storage, insulation, and cell membrane structure.
Nucleic Acids - Answer Store and transmit genetic information.
Vitamins - Answer Support metabolic processes, act as coenzymes.
Identify the purposes for ingesting nutrients. - Answer To provide energy → For synthesis of
ATP
To make new molecules
Regulation of body processes
Herbivores - Answer Eat only plants
Carnivores - Answer Consume animal flesh or fluids
Omnivores - Answer Eat both plant and animal material
Autotrophs - Answer Organisms that produce their own food from inorganic substances.
Energy Source: Use sunlight (photosynthesis) or chemical energy (chemosynthesis).
, Examples:
- Plants (e.g., oak tree, grass)
- Algae
- Cyanobacteria
Heterotrophs - Answer Organisms that must consume other organisms to obtain nutrients
Energy Source: Derive energy by ingesting organic compounds.
Examples:
- Animals (e.g., humans, lions, insects)
- Fungi
- Most bacteria
- Protozoa
Suspension/Filter feeding - Answer Filter organic matter out of water (or the air)
Bivalve molluscs, sea squirts, baleen whales
Terrestrial suspension feeding - Answer Spiders create a web that catches insects
Flamingoes small krill and other organisms out of the water
Bulk Feeding - Answer Carnivores, herbivores, omnivores
Eat food in large pieces
Carnivores can be divided into predators and scavengers
Carnivores generally do not chew their food
Herbivores are highly adapted for chewing
Fluid feeding - Answer Lick or suck fluid from plants or animals
Do not need teeth except, perhaps, to puncture an animal's skin
Evolved independently in many types of animals
Hummingbird sucks nectar from plants
Leech sucks blood from its host
Detritivores - Answer Eat dirt
Have digestive systems that can filter out organic materials
