chapter 10 bio

Question 1

abiotic

Answer 1

non living

Question 2

biotic

Answer 2

lliving

Question 3

different adaptations for hot env: structural

Answer 3

insulation, SA:V

Question 4

different adaptations for hot env: structural - insulation

Answer 4

the more insulated an animal is, the harder it is for the animal to release heat into the env - thickness of fat & fur

Question 5

different adaptations for hot env: structural - SA:V

Answer 5

high ratio: releases or absorbs large amounts of heat in little time, allowing body temp to quickly change, low ratio: beneficial for animals where are constantly exposed to direct sunlight or cant escape

Question 6

different adaptations for hot env: physiological

Answer 6

1. metabolic heat
2. surface blood flow
3. incease water input
4. decrease water output
5. evaporative cooling

Question 7

different adaptations for hot env: physiological - metabolic heat

Answer 7

spend alot of energy producing heat, but in desert they must have effective strateies to release excess heat

Question 8

different adaptations for hot env: physiological - suface blood flow

Answer 8

When internal temperatures rise, blood vessels near the surface dilate and total surface blood flow increases – cooling the animal

Question 9

different adaptations for hot env: physiological
- increase water input

Answer 9

due to low availability of urface water, most desert animals obtain their water from other sources

Question 10

most desert animals obtain their water from other sources- decrease water output

Answer 10

excreteting highly concentrated wastes to cnserve water

Question 11

most desert animals obtain their water from other sources - evaporative cooling

Answer 11

sweating, panting

Question 12

Structural adaptations

Answer 12

special physical features that make an organism well suited to the environment it lives in

Question 13

physiological

Answer 13

internal features of an organism that enable them to survive in their environment

Question 14

behaviourable

Answer 14

something an animal does usually in response to some type of external stimulus in order to survive

Question 15

different adaptations for hot env: behaviorable

Answer 15

1. evading extreme condition
   2.enduring extreme conditions

Question 16

different adaptations for hot env: behaviorable - evading extreme conditions

Answer 16

seek out shade or retreat to a burrow system.

Question 17

different adaptations for hot env: behaviorable - enduring extreme conditions

Answer 17

when hot, aniaml have ways to deal w it by releasing waste and heat into env, taking breaks during hot hours or licking and wallowing

Question 18

adapting to desert plants

Answer 18

in order to survive hot n dry env they must decrease heat intake, maximise their water uptake, minimise their water loss

Question 19

plants: increase water uptake

Answer 19

extensive deep root systems to reach groundwater reserves, spread roots horizontally to absorb the maximum amount of surface water during the brief periods of rain

Question 20

plants: water storage

Answer 20

collect huge amount of water during season & storing it

Question 21

plants: mini water loss

Answer 21

through stomata
