1. Explain why the factors is an essential factor for living organism.

2. Describe what would happen to organisms if the factor is present or absent in the environment. Do take some time to discuss the extremes.

1. Temperature is too high.

   Plants and Animals cannot survive as plants will wilt as water is loss through the stomata through evaporation and the plants will not be able to make food and die.

   Animals will dehydrate and die.

2. If temperature is too cold

   temperature drops to 0^oC and below, water will freeze and animals will not have enough water to drink.

   Plants and animals will also freeze and die.

Too warm: we will melt and plant will die leading to animals dying

Too much food: we will face overpopulation and then will have a shortage of food

To hot not be able to live too

If we have too much water, our blood will get diluted

If we have to little water, we will suffer from dehydration

When there is no food, living organisms will die because of the lack of energy

Too little air: we cant breathe and cannot respirer and cannot carry out life processes, as there is too little oxygen.the atmostphere will disappear too

1. Too little food means less energy. The animals and plants cannot carry out too many life processes. The animals will die of starvation eventually.

2. Too much food will turn into fats. Harder to do exercise and lack of mobility.

3. If there is no food, animals and plants will not be able to respire and make energy. They will not be able to carry out life processes. They will die after a while.

2) If food is absent in the environment, the animals and humans will starve to death.

Too much food: animals will grow too fat

1. Food is needed for survival. without food living things do not have the energy to carry out life processes

2. The immune system will be vastly affected causing a decrease in health and stomach pains

When the temperature is too high, there would be global warming, increasing carbon dioxide, causing animals to go extinct

Too little light would make us walk into walls or off buildings

If it is too cold, llewelyn will die to hypothermia

We will not have any food to digest for respiration and release energy to carry out life processes

Too much food:

The excess food is stored as fat, it will also cause us to gain weight which is not healthy

No air: we will die

Too little water: we will die of dehydration, and plants too

When there is too much water, there would more flooding and some islands will disappear

Too little water: people will die of dehydration

Too little animals would affect the food web and cause all the animals on earth to dai

Without carbon dioxide plants cannot photosynthesis and they will wilt causing the environment to be filled with too much co2 n not enough o2

Oxygen is also used to make energy. Too little oxygen causes too little energy,thus we will not have enough energy to carry out life processes. Without oxygen, we will choke to death

Too little light: cannot see

The earth will be flooded because of too much water and all land animals will drown.

Too little: plants cannot undergo photosyntesis and die leading to animals dying

If the temperature is too hot, plants will wither and die while animals will not have enough water to survive.

We also need light to see.

Less living things: living things might die

To little air:

We will suffocate and die>:)

Too many prey: plants will decrease and ecosystem will collapse

Too little plants: prey, then predators will decrease and ecosystem collapse

If other living things help us in many ways, like bees helping us get honey, we will be able to have enough food

2.If the temperature of the surroundings is too hot, then the animals will gain too much heat and suffer from heatstroke.

If there is no light, plants cannot carry out photosynthesis and make food to carry out life processes. Animals will also not be able to see.

If there is too much food we will become overweight and eventually die.

Too much water can result in flooding which will cause decrease in land size

However, some type of animals will decrease as other organisms will feed on them

Too little water causes us to have dehydration which can cause death ,it also causes plants to wilt and perish

If there is too little air, we will suffocate.

1) Too little water results in droughts, and since plants, animals and humans need water to carry out life processes. Plants need water for photosynthesis. Without water, the plants will dry up and die.

Light produces heat which will result in the universe being tooooooo hot >:)

To little light：

Not bright enough to see and do daily activities

If it is too cold, living things will freeze and die

Too much light, it will be to hot for us, letting us lose more water.

What happen if there is air pollution?

• More carbon dioxide, respiration problems

• global warming - increase in temperature

Insects that eat crops or any herbivores

2)Cactus,camel,scorpions,meekat,snake

Cactuses and camels

Any herbivores can live in the field( if farmers dont find them) and carnivores may eat the herbivores. The temperature, weather, light and air is all good for animals herbivore and carnivore alike to live there.

Humans, dogs, deer

Air

Temperature

Other living things

Water

Light

Food : fish and plants

Air : more water vapour in the air due to consistent evaporation

Temperature : cooling temperature

Other living things : fish, plants, crocodiles , frogs n bacteria

Water: sufficient water for fish n plants to grow

Light: low amount of received by submerged plants

There is a pond where fishes and plants can grow in and reproduce.

Types of organisms that will survive in the habitat:

Algae, fishes, plants, bacterias, viruses

-surplus of food

-if wheat can survive, there must have water

-have air

-wheat will provide shade, less heat & light

Living things: wheat, grass, rats, moles, birds, anything that feeds on wheat

2.frogs,lily pads,Dragonflies,moss

2) If it is too cold we will shiverand die

2.birds, frogs, fish and insects.

F- The insects are eaten by the frogs and the plants get food from the sun and the birds get food from the fruits on the plants.

A- There will be enough air for the animals there

T-It would be cooling from the shade of the trees and plants and high concentration of water vapour in the air because it is near a water source.

O- There will be fungi such as mushrooms, algae in the water and bacteria.

W- There is water from the pond.

L- There is light from the sun

There will be snakes,frogs,birds and fishes.

What does temperature affects?

What happen when it is too hot? What would be the unfavourable environment and what would happen to the organisms?

What happens when there is a drought or floods due to extreme amount of water?

What would the organisms do?
