Pollution in the Oceans

Pollution in the oceans

Pollution in the oceans mean that garbage is polluting the oceans, but not only garbage is polluting the oceans but oil spills, toxic wastes and garbage three of them are polluting the most.

 

The grey spots you see in the picture are the famous garbage spots that were known to be as big as Hawaii last year but today the garbage spots have grown so large that Hawaii is a small spot under it.

 

As you can see I have enlarged the photo for it to be easier to read for you.

 

Now the animals are confusing them as their food because some of the garbage looks as if its their food, for example surfboards look like large fish or seals sharks try to eat them and albatrosses confuse small toxic wastes as zooplankton and eat them, and a turtle's favorite food is jellyfish which they confuse for plastic bags.

Characteristics of Living things



Characteristics of Living things

We live on a planet called earth which is the only planet which can keep life on it. There are billions of living things on earth from gigantic whales to small microbes. Lets see how to spot the difference between living and non living things.

Living things are things that are alive things that are alive must have these characteristics:

Movement: Yes a little bit

Growth: Yes

Reproduction: Yes

Needs food: Yes ( Chloroplasts a special sugar )

Respiration: Yes

Excretion: Yes ( releases air and water )

Sensitivity: Yes ( to light )

These are the 7 main characteristic that a living thing has, if it doesn't have one of these its not a living thing.

Movement

All living things can move on their own even plants - they just move very slowly.

Nutrition means energy, energy comes from proteins and vitamins. All living things need energy to do work. Even breathing takes a little bit of energy

Excretion

All living things throw wastes out of their bodies. The wastes are the things that doesn't have any nutrition left in it, it is commonly said as poo, or excretion means throwing wastes from our body

Respiration

Respiration is also called as breathing. Every living thing needs oxygen to breath

Sensitivity

Sensitivity means sense. When we touch a touch me not it closes its leaves because it senses our touch

Reproduction
