Q

What is an ecosystem?

A

An ecosystem is an unit that includes all the biotic (living) parts (e.g: plants and animals) and the abiotic (non-living) parts in an area.

Q

What is a decomposer?

A

A decomposer is an organism that gets its energy by breaking down dead material, e.g) dead producers, dead consumers or fallen leaves. Bacteria and fungi are decomposers. This returns nutrients to the soil, where they can be used by plants.

Q

Give an example of a small scale ecosystem:

A
  • A hedgerow ecosystem includes the plants that make up the hedgerow, the organisms that live in it and feed on it, the soil in the area and the rainfall and sunshine it receives.
  • The producers include the hawthorn bushes and blackberry bushes.
  • The consumers include thrushes, ladybirds, spiders, greenfly, sparrows and sparrowhawks.

Q

How are different parts of ecosystems interdependent

A

Some parts of an ecosystem depends on the others, e.g: consumers depend on producers for a source of food and some depend on them for a habitat (a place to live). So, if one part changes it affects all the other parts that depend on it.

Q

Example of ecosystems being interdependent

A

Hot, dry summer –> reduced plant growth –> Fewer berries for birds in the winter –> Number of sparrows and thrushes fall –> Fewer birds for sparrowhawks, so number of sparrowhawks fall

Q

Remember this:

A

The climate in an area determines what type of ecosystem forms. So different parts of the world have different ecosystems because they have different climates.

Q

Where are grasslands found in the world?

Q

Where are polar areas found?

A

Found around the north and south poles.

24
Q

What is the climate like of a polar area?

A
  1. Polar areas are very cold. Temperatures are usually less than 10°C. Winters are normally below -40°C and can reach almost -90°C.
  2. Precipitation is low - no more than 500mm a year (mainly in the summer).
  3. There are clearly defined seasons - cold summers and even colder winters.
25
Q

Things about animals in the polar area:

A
  1. There are relatively few different species of animals compared with other ecosystems.
  2. Polar bears, penguins and marine mammals like whales, seals and walruses are examples of animals that are found in the polar regions.
26
Q

Things about plants in the polar area:

A
  1. There are very few plants - some lichens and mosses are found on rocks and there are a few grasses and flowering plants on the coast where it’s warmer,
  2. Plants grow slowly and don’t grow very tall - grasses are the most common plants. Closer to the poles, only mosses and lichens can survive.
  3. Some small, short trees and shrubs grow in warmer, sheltered areas.
27
Q

What is the climate like in hot deserts?

A
  1. Very little precipitation - less than 250 mm per year. When it rains can varie a lot - it might only rain once every two or three years.
  2. Temperatures are extreme - they range from very hot in the day (e.g: 45°C) to cold at night (below 0°C).
28
Q

Things about plants in hot deserts:

A
  1. Plant growth is sparse due to the lack of rainfall. Plants that do grow include cacti and thornbushes.
  2. Plant roots are often very long to reach deep water supplies, or spread out wide near the surface to catch as much water as possible when it rains. Some plants (e.g: cacti) have fleshy stems and thick waxy skin to cope with the dry climate.
29
Q

T

Things about animals in hot deserts:

A
  1. Hot deserts are home to lizards, snakes, insects and scorpions. Mammals tend to be small, e.g: kangaroo rats. Many birds leave during the hottest weather.
  2. Animals are adapted to cope with the harsh climate. Many animals are nocturnal so they can stay in burrows or in the shade during the day. Some bigger animals have evolved to lose very little water and to tolerate dehydration, e.g: camels.
30
Q

What is the climate like in grasslands?

A
  1. Savannah grasslands have quite low precipitation (800-900 mm per year) and distinct wet and dry seasons. Temperatures are highest (around 35°C) just before the wet season and lowest (around 15°C) just after it.
  2. Temperature grasslands have hot summers (up to 40°C) and cold winters (down to -40°C). They receive 250-500 mm precipitation each year, mostly in the late spring and early summer.

  2. Thick canopy spring- compete successfully with other plants for sun light
  3. Lose leaves winter , protect from damage by strong winds and snowfall winter
