Core Biology Chapter 4 AQA

?
5 things plants need to survive
Carbon dioxide, water, oxygen, nutrients - mineral ions from soil
1 of 18
Define adaptation
Special features of organisms
2 of 18
What do adaptations allow orgasisms to do
To survive in a particular habitat, even when conditions are extreme
3 of 18
What are extremophiles
Micro-organisms that are adapted to live in conditions where their enzymes wouldnt usually work as they would denature
4 of 18
How are animals in cold climates adapted to the environment
Have thick fur and fat under the skin to keep them warm
5 of 18
What can bigger animals do
Conserve energy easier but find it harder to cool down
6 of 18
Why may some animals hunt/feed at night
To keep them cool during the day
7 of 18
Why do smaller plants flower before trees are in leaf?
To ensure they get enough light, water and nutrients
8 of 18
How do plants spread their seeds
Use animals to spread seeds and fruit, or use wind or mini explosions
9 of 18
Why do plants spread their seeds as far as possible
So they dont end up competing with eachother
10 of 18
How do female fig wasps pollunate
They have specially shaped heads and oviposters to let them place eggs inside flower
11 of 18
How are the star nosed mole and venus fly trap adapted for survival
Mole - sensitive to touch and smell- detects food underground, venus fly trap - brightly coloured, sticky nectar to trap prey
12 of 18
Name 3 non living environmental factors
Temperature, rainfall, light, oxygen levels
13 of 18
Name 3 living environmental factors
Arrival of new predator or disease, introduction of new plants - new food/habitats
14 of 18
What are lichens and what do they do
Indicate levels of air pollution - sulfer dioxide, More lichens growing the cleaner the air
15 of 18
What are freshwater invertebrates and what do they do
Indicate levels of water pollution.
16 of 18
5 pieces of equipment used to monitor non living changes
Rain gauges, thermometers, data loggers, ph/oxygen sensors
17 of 18
Why do some birds fly further north to find nesting sites
Climate change caused it to be warmer
