Question 1

What are the 8 things that living organisms can do? Hint: MRNGREWW

Answer 1

Movement
Reproduce
Need Nutrition
Grow
Respond to change
Exchange gases
Waste
Water

Question 2

What are the seven levels of classification for living organisms?

Answer 2

Kingdom-king
Phylum-phillip
Class-crawled
Order-over
Family-four
Genus-gooey
Species-snails

Question 3

What is the difference between autotrophs and heterotrophs?

Answer 3

Autotrophs can produce their own food using photosynthesis (plants) while heterotrophs like fungi and animals can’t.

Question 4

Who created the dichotomous key and the seven levels of classification?

Answer 4

Carl Linnaeus.

Question 5

What are the two main groups that animals are separated into?

Answer 5

Vertebrates and invertebrates.

Question 6

What are the 5 main classes and their characteristics?

Answer 6

Class Aves (Birds)
-endothermic, feathers, scaly legs and lay eggs with hard shell
Class Pisces (Fish)
-ectothermic, covered with scales/fins
Class Reptilia
-ectothermic, have lungs to breathe and lay eggs with a leathery shell
Class Amphibia
-ectothermic, soft slimy, lay eggs without shells
Class Mammalia
- hair or fur, give birth to live young, female lactate, endothermic.

Question 7

What are the three different types of mammals?

Answer 7

1. Placentals
2. Monotremes
3. Marsupials

Question 8

What is the definition of endotherms and ectotherms?

Answer 8

Ectotherms- body temperature changes with the environment.

Endotherms- constant body temperature.

Question 9

What are the five kingdoms?

Answer 9

1. Monera
2. Animalia
3. Fungi
4. Plantae
5. Protista

Question 10

What are the cells like in the five kingdoms?

Answer 10

Monera- the simplest, smallest thing, unicellular, has a cell wall.
Protista- more complex than Monera, can be multicellular or unicellular. The study of Monera and Protista is Microbiolgy.
Fungi- heterotrophic, glow filaments called ‘mycelium’. The study of fungi is called mycology.
Animalia- multicellular, cell membrane and nucleas. Heterotrophic.
Plantae- cell wall and nucleas, chloroplasts- photosynthesis, autotrophic, multicellular.
The DNA and genes are found in a nucleas.

Question 11

What are the nine phylum a for animals?

Answer 11

Vertebrates:
-chordates
Invertebrates:
-athropoda eg. Insects (paired and jointed legs, segmented bodies, exoskeleton.)
-Poriferans eg. Sponges (spongy body with holes, found in water, rocks)
-molluscs eg. Snail, octopus, anemone (Soddy body, protective shell)
-cnidarians eg. Jelly fish (soft hollow body, lives in water and has tentacles.
-worms (Annelids, Platyhelminthes and nematodes) segmented, flat, round, soft long body
-Echinoderms eg. Starfish (rough spiny skin, radial symmetry, arms radiate from center, found in sea)

Question 12

What are plants that do and don’t form flowers called?

Answer 12

Plants that form flowers: Angiosperms
Plants that don’t form flowers: gymnosperms
Types of angiosperms:
-monocots (one leaf, veins in straight lines)
-dicots (two leaves, veins going out)

Question 13

What is the definition of a food chain?

Answer 13

Food chains show the flow of food in an ecosystem.

Question 14

Where do plants get there energy from?

Answer 14

Plants get their energy from the sun’s sugars, through photosynthesis. Because they aren’t consumers they are always at the start of food chains and called producers.

Question 15

What are four ways that human activity can affect local habitats?

Answer 15

Deforestation
Land degradation
Urban Sprawl
A changing Climate

Question 16

What three animals can pollinate plants?

Answer 16

Insects, birds and bats.

Question 17

What are examples of deco losers and where do they get their energy from?

Answer 17

Decomposes get their energy from the nutrients found in dead organisms, some examples of decomposers include fungi, bacteria and invertebrates like slugs and snails.

Question 18

What order do the consumers come in?

Answer 18

Producers>primary consumers>secondary consumers>tertiary consumers>apex predator!
Or, first-order consumer, second-order consumer, and third-order consumer. With the carnivores, the top one is called top carnivore.
In food chains and food webs, the arrow always point to the predator, the consumer

Question 19

What’s an example of an indicator species and what are they?

Answer 19

An indicator species is one that indicates environmental, and human health. An example of one is the cane toad.

Question 20

What natural things help clean water?

Answer 20

Wetlands and forests.
