animals & ecosytems Flashcards
who does not have back bones
invertebrates
EX. Insects, flat worms, snails
invertebrates with pores all over their bodies
sponges
sponges may have spikes called
spicules
spend adult life attached to a single spot
sessil
- asymmetric body plan
- few specialized cells uses •flatulent to move water through body for filter feed
- reproduce bye buddy or sexual reproduction in larva develops
- oxygen from water by diffusion
sponges
invertebrates that are complex than sponges
cnidarians
example of cnidarians
jellyfish, sea anemones, coral
- bodies are made of mesoglea (jelly) with tentacles
- stinging cells are used to capture prey and also defense
- food comes in and exits through the same hole
- specialized tissue and nerve nets
- radially symmetrical: polyp/medusa body plans
- reproduce through budding or sexual reproduction
Cnidarians
example of a flatworms
planarians, flukes, tapeworm
- some are parasites
- some live in ponds, damp soil’s, or ocean
- flat bodies: bilaterally symmetrical
- One opening for mouth/Waste
- can regenerate
- obtain oxygen, gets rid of waste through diffusion
flatworms
example of roundworms
pinworms, heart worms
- live in moist environments
- some are carnivores or herbivores or parasites
- digestive system: tube that opens at both ends
roundworm
who has back bones
vertebrates
ex. human, bird, snake
example of annelids (segmented worms)
earthworms, leeches
- bodies are made of sections called segments
- one-way digestive system (mouth, anus)
- closed circulatory system: blood stays in vessels
- setae: bristles to help move through the dirt
annelids (segmented worms)
example of mollusk
snails, Slugs, oysters, squids
- invertebrate with hardshell, protecting the outside
- internal organs are covered by mantles
- move with a foot
- bilaterally symmetrical
- kidney: remove Waze that is produced by the cells
- gill: Remove oxygen from water
- radula: flexible ribbon that helps scrape food from surfaces
mollusk
three types of Mollusks
gastropods, bivalves, cephalopods
- use foot to move
- foot oozes slippery mucus
- Open circulatory system: blood is not contained in vessels
- Single shell or no shell
gastropods- mollusks
example of gastropods-Mollusks
Snails, Slugs
example of bivalves-mollusks
Clams, Oysters, mussels
- two shelled
- no radula, they are filter feeders
- some move as adults some Sessile
bivalves- mollusks
- have tentacles
- nautiluses have external shells
- squid and cuttlefishes have internal shells
- octopuses have no shell
- jet propulsion to move
cephalopods-mollusks
what is the largest phylum
arthropods
what protects the animal, prevents evaporation of water, tough but flexible(chitin)
exoskeleton
arthropods have ________ bodies
segmented
an example of arthropods
centipede, millipedes
- Joints give flexibility
• Mouthparts: feeding
• Antennae: sense organs
• Claws: catching prey and defending against predators - Wing: flying
appendages
•2-3 body sections
•5 or more pairs of legs
• Have gills
crustaceans
example of crustaceans
lobster, shrimp, crayfish
example of arachnids
spiders, ticks
- combined head and chest
•hind section
* 8legs
•Have antennae
arachnids
example of echinoderms
Brittle Stars, Sand Dollars, Sea Urchins, sea cucumbers
•Spiny skinned animals
•Radially symmetrical
• Invertebrates that live on the ocean floor
•Endoskeleton: spiny internal skeleton made of plates
• Contains calcium called test
echinoderms
• fluid-filled tubes within its body
•Used to move tube feet
•Ends of the tube may have suction cups
•Suction cup: used to grip the surface and capture food
echinoderms
who has No head end – adapted to respond to food, mates, or predators
echinoderms
Eggs fertilized in water after the sperm is released
reproduction
who eats mollusks, crabs and other echinoderms, Can regenerate ( regrow ) lost body parts like arms
sea stars
has an endoskeleton (internal skeleton), mammals, and has different body temperature depending on the organism
chordata
have a body temperature of their environment (fish, amphibian, retile)
ectothermic
have a stable body temperature that is warmer than their environment (bird,mammals)
endothermic
three types of fishes
jawless fishes
Cartilaginous fishes
Bony fishes
- Ectothermic vertebrates
•Lives in water
• Have fins for moving/swimming - Oxygen through gills
• external fertilization
fish
examples of amphibians
frogs, toads, salamanders
• Moist skinned
•Ectothermic vertebrates § Early lives; in water
• Adulthood; on land
•Reproduce; in water
• Strong skeletons and limbs for moving on land
amphibians
•Ectothermic vertebrates
• Entire life spent on dry land
reptiles
examples of reptiles
snakes, turtles, alligators
•Endothermic vertebrates
• Have feathers
• Most fly
birds
- Endothermic vertebrates
- Covered with hair or fur
- Four chambered heart
mammals
who has three groups called Monotremes, Marsupials, and
Placental
mammals
what mammal lays eggs
monotremes
platypus
what mammals give birth to young that developed in mothers pouch
marsupials
koalas, kangaroo, etc
what mammals developed fully inside the mothers womb
placental mammals
humans, bears, giraffes, etc
living factors
ex. plants, animal
biotic
nonliving factors
ex. water, soil
abiotic
Energy transfer among specific organisms
food chain
Energy transfer among all organisms
food web
make its own food through photosynthesis
autotroph
eat or absorb food
heterotroph
the position that an organism occupies in a food chain
trophic level
