Flashcards in Science- Classification And Food Chains Deck (20):
What are the 8 things that living organisms can do? Hint: MRNGREWW
Respond to change
What are the seven levels of classification for living organisms?
What is the difference between autotrophs and heterotrophs?
Autotrophs can produce their own food using photosynthesis (plants) while heterotrophs like fungi and animals can't.
Who created the dichotomous key and the seven levels of classification?
What are the two main groups that animals are separated into?
Vertebrates and invertebrates.
What are the 5 main classes and their characteristics?
Class Aves (Birds)
-endothermic, feathers, scaly legs and lay eggs with hard shell
Class Pisces (Fish)
-ectothermic, covered with scales/fins
-ectothermic, have lungs to breathe and lay eggs with a leathery shell
-ectothermic, soft slimy, lay eggs without shells
- hair or fur, give birth to live young, female lactate, endothermic.
What are the three different types of mammals?
What is the definition of endotherms and ectotherms?
Ectotherms- body temperature changes with the environment.
Endotherms- constant body temperature.
What are the five kingdoms?
What are the cells like in the five kingdoms?
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.
What are the nine phylum a for animals?
-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)
What are plants that do and don't form flowers called?
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)
What is the definition of a food chain?
Food chains show the flow of food in an ecosystem.
Where do plants get there energy from?
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.
What are four ways that human activity can affect local habitats?
A changing Climate
What three animals can pollinate plants?
Insects, birds and bats.
What are examples of deco losers and where do they get their energy from?
Decomposes get their energy from the nutrients found in dead organisms, some examples of decomposers include fungi, bacteria and invertebrates like slugs and snails.
What order do the consumers come in?
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
What's an example of an indicator species and what are they?
An indicator species is one that indicates environmental, and human health. An example of one is the cane toad.
