-Format: Multiple-choice / Flashcard
Question 1: Decomposers (bacteria and fungi)
Answer:
AKA: saprotrophs, they break down organic matter and release minerals back into the soil
Question 2: Protista
Answer:
Simplest eukaryotes (that is, their cells have nuclei) Includes protozoa, unicellular and multicellular algae, and slime and water slime molds Ancestor organisms to plants, animals and fungi Many can move around by means of flagella Some are also photosynthetic
Question 3: Commensalism
Answer:
A relationship between two organisms in which one organism benefits and the other is unaffected
Question 4: Primary Consumer
Answer:
AKA: Herbivores
Subsist on producers such as plants Ex. grasshoppers, deer, cows, and rabbits
Question 5: Eukaryota Domain
Answer:
All living things who cells have nuclei are in this domain Almost all multi-celled organisms (including plants, animals, and fungi) are in this domain
Question 6: Tertiary Consumers
Answer:
AKA: Top carnivores, apex predators
Capable of eating secondary consumers Can also be omnivores Ex. Lions, wolves, sharks, and humans
Question 7: Phylum in Living thing Classification
Answer:
Contains several related classes
Ex. Human Beings: Chordata
Question 8: Animalia
Answer:
Produce energy by consuming other organisms, so they are called consumers Can be either vertebrates( which belong to phylum Chordata) or invertebrates such as mollusks, arthropods, sponges, coelenterates, worms, etc.Human beings belong to this kingdom
Question 9: Community of Ecosystem
Answer:
Contains many populations of organisms with each population falling into one of several roles in the food chain
Question 10: Kingdom in Living Thing Classification
Answer:
Contains several related phyla
Ex. Human Beings: Animalia
Question 11: Secondary Consumers
Answer:
AKA: Carnivores or predators
Subsist mainly on primary consumers Ex. birds of prey, foxes, and snakes Can also be omnivores that consume producers and consumers (chickens, rats, sea otters)
Question 12: Biosphere
Answer:
Zone of planet Earth where life naturally occurs, including land, water, and air, extending from the deep crust to the lower atmosphere
Question 13: Mutualism
Answer:
A relationship between two species in which both species benefit
Question 14: Parasitism
Answer:
A relationship between two organisms of different species where one benefits and the other is harmed
Question 15: Ecosystem
Answer:
System made up of a community of animals, plants, and other organisms as well as the abiotic (non-living aspects of its environment
Question 16: Tiers of Living Thing Classication
Answer:
Goes from broadest similarity (domain) to narrowest (species)
(1) Domain: Dear
(2) Kingdom: King
(3) Phylum: Phillip
(4) Class: Came
(5) Order: Over
(6) Family: For
(7) Genus: Good
(8) Species: Soup
Question 17: Six Animal Kingdoms
Answer:
Monera Protista Fungi Plantae Animalia
Question 18: Biome
Answer:
Major life zone of interrelated species bound together by similar climate, vegetation, and animal life
Question 19: Plantae
Answer:
Have ability to photosynthesize, so they are called producers Four major phyla: Bryophyta, or masses; Tracheophyta, which have vascular systems; gymnosperms; and angiosperms
Question 20: Producers (mainly plant life)
Answer:
AKA: autotrophs
They make their own food via photosynthesis
Question 21: Orders in Living Thing Classification
Answer:
Contains several related families
Ex. Human Beings: Primates
Question 22: Species in Living Thing Classification
Answer:
Contains organisms so similar that they can only reproduce with one another to create viable fertile offspring
