Fossil fuels and green house gases which burn holes in the ozone layer of the atmosphere causing global warming
Living things cannot live without eachother due to the food chain, if an animal loses it's food so will his predator and so on. Soon they will end up extinct, this is why it's important to take care of animals.

1. An example of secondary consumer is snake. Secondary consumers are the ones who eat the primary consumers, which makes them carnivore.
2. Photosynthesis is a process used by plants and (some other organisms) that converts water (H2O) and carbon dioxide (CO2) with the presence of sun energy (collected in the chloroplasts) into chemical energy that is later stored in sugars (carbohydrates). Organisms that do the photosynthesis are called autotrophs (produce food by themselves).
3. The energy pyramid represents energy flow in a community, where the different levels represent different groups of organisms.
The food chain is a circulation of energy that comes from the sun and passes from the producer organisms to the primary consumer, secondary and tertiary consumer organisms.
4. For example, plant is producer that is eaten by primary consumer-herbivore (e.g. bugs). Than secondary consumer-carnivore (e.g. snake) eat that herbivore and than is being eaten by tertiary consumer (apex predator that have no natural predator).
5. One trophic level gets only 10% of the energy of the previous level. So, if the plant have 10.000 units of energy and is eaten by rabbit, rabbit gets 1000 units of energy, and when the fox eats an rabbit, it gets 100 units of energy.
6. Trophic level is the position of an organism in the food chain.
