Task card eight - Ecosystem Earth

What is the difference between first, second and third order consumers?The first order consumer be insects, small animals like fish and bugs so the second order consumer would be something that eat or live off the first order consumer so that would be birds, small or medium size fish, smalls mammals (kangaroo). The third order consumer’s food is mainly base on meat so it would be lion, tiger, humans, shark.

What is a trophic level?
A tropic level is different categorizer’s name in a pyramid where it illustrates the first, second and third order consumer and each of them is a different tropic level.

Prey and predators

Hi

two examples from the diagram of predators is edible crab and herring gull, and 2 examples from the diagram of prey is worm and seaweeds

By Jack

what happens to the amount of energy as it travels through an ecosystem?

As the energy travels through an energy pyramid it decreases as most of is released as waste and respiration by the other organisms in the energy pyramid.

Carbon Cycle - Task card 10

..The carbon cycle..

1.

All living things are made up of carbon, it is part of the ocean, air, animals, humans and surprisingly even rocks. Because the Earth is a dynamic place, carbon does not stay still. It is always on the move!

- The full name for Carbon is Carbon Dioxide. -

The carbon dioxide molecule consists of one Carbon atom and two oxygen atoms.

The carbon cycle is the name given to the system in which carbon fits into our world. Basically, Plants use carbon and sunlight to make their own food to grow, The carbon becomes part of the plant. This is why tree's are important in our world because they are practically carbon eaters and oxygen distrabuters. However, when plants die and are decomposed, the carbon that was once trapped in the tree, is let out again and goes back into the earth. When deforostation takes place, a large amount of Carbon is released into the environment all at once which is bad because there is now more carbon and less oxygen being produced. When trees fall and get buried under the ground they slowly turn into fossil fuels made up of carbon like coal and oil, this process happens over millions of years. When humans burn fossil fuels, most of the carbon that has been buried under the ground for millions of years quickly enters the atmosphere as carbon dioxide. (and thats just the cycle for plants and trees)

Every living and non living thing in our world is or produces carbon.........(((will finish next lesson!!!)))

Exercises 4,5,6page 252

4) in an urban ecosystem the humans controll it alot more, we farm our food and have water stored for us but in a natural ecosystem the animals have no control over what happens and have to find food and water for themselves. and they have to protect them selves from other animals.
5)some plants might grow better in higher temp
eratures and cause them to overbreed or even out breen the plants whic dont do very well in heat.
6) the amount of insects decreased when alot of trees and bushes were planted because there is more room for animals to come and live in this ecosystem. The insects being at the bottom of the food chain are now being eaten by all the new predators like birds.

what does a decomposer do?

we define a decomposer to be an organism normally a bacteria or fungus that eats on and decomposes dead animal or plant matter.

eating habits

No offence intended. if you are offended I will change it.

Herbivores (human name: vegans) these creatures eat only plants(producers) and are first order consumers e.g. deer

Omnivores (human name: every day humans) these creatures eat both plants and meats e.g. most humans

Carnivores (human name: meat lovers) these creatures are the top of the food chain and eat only meat. they are 3rd order consumers e.g. lions and sharks.

remember no offence intended
