IN EVERY SPECIES I THINK

25
What are the names of areas where organisms are found?
Habitat/ecosystem
26
Know that organisms are adapted to where they live
THIS IS AN ANSWER
27
How are some organisms adapted to living in different habitats?
Figure this out yourself. Examples: Long fur in cold environments.
28
What are some adaptations for living in hot and dry, cold and underwater areas?
Hot and dry: long ears to lose heat, short fur | Cold: Long fur, layer of fat (it's not blubber), small ears to conserve heat.
29
What changes happen in an environment?
Daily changes: Temperature change, amount of light | Seasonal: Temperature, amount of light, wind, amount of water.
30
How do organisms respond to daily changes?
Sleep at night, open flowers in different times, sleep in the morning, stuff like that.
31
How do plants respond to seasonal changes?
Protect buds, shed leaves
32
What are the meanings of the words predator, prey, herbivore and carnivore?
Predator: An animal that preys on others. Prey: An animal that is hunted and killed Herbivore: Only eats plants Carnivore: Only eats meat Omnivore: Eats both plants and meat
33
What are some adaptations of predators?
Long legs to run faster, sharp claws, teeth, beak, better senses (eyesight, scent, hearing) camouflage?

38
What equipment is used for sampling?
Quadrat, sweep net, pooter
39
What are some sampling methods?
Use a Quadrat to 'cut out' a piece of ground in a habitat and note how many organisms live in that habitat
40
How do you estimate population sizes?
Take some measurements about how many organisms live in a particular area using a quadrat. Get an average number then yup k.
41
How do people study habitats?
IDK | if it comes up in the test just write the sampling stuff.
42
How do you follow instructions? IDK WHY IT WAS ON THE TASKSHEET
i don't think i can tell you that btw this was on the task sheet YOU JUST FOLLOW IT PPLL snoopy out
43
How do you use a quadrat?
