1. The trophic levels of every food web always start with the producers.
2.Plants are also known as producers because they are the start of the food chain.(considering if you are looking at a food chain that starts with plants)
3.The energy transferred through the food web as you go up the trophic levels, goes down. 
4. A bioaccumulation is when toxins build up in a food chain.
5. A food chain is different from a food web because a food chain always start with producers, which are often green plants, while a food web is a network of interconnected food chains]]> 2017-12-30 05:53:30 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218175124 cchan11 https://padlet.com/cchan11/9eo6sdxfb1/wish/218175427 Does it really matter???]]> 2017-12-30 06:30:14 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218175427 cchan11 https://padlet.com/cchan11/9eo6sdxfb1/wish/218175502 The three main factors that you must consider about when thinking about a sustainable development is Social progress, economic development and climate and environment. Why should we care about them??? Well, lets start with Social progress. We all are important to nature but we need to have equal  opportunities, education, safety, food and medicine. For economic development, We have to use our natural resources smartly and to be aware of how it’s made, and lastly, for climate and environment, this system ensures that the temperature is correct and that the atmosphere emits exactly the right amount of solar energy. ]]> 2017-12-30 06:37:25 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218175502 cchan11 https://padlet.com/cchan11/9eo6sdxfb1/wish/218175579 This video will tell you about it!]]> 2017-12-30 06:43:38 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218175579 cchan11 https://padlet.com/cchan11/9eo6sdxfb1/wish/218175702 Conservation take place when people find out that a specie of animal is almost extinct]]> 2017-12-30 06:55:13 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218175702 cchan11 https://padlet.com/cchan11/9eo6sdxfb1/wish/218175974 There are a five types of natural resources that we could conserve: Animals, plants, minerals, fuels and fresh water. But how do we conserve them??? Well, here are some examples. For animals, we could help them by setting nature sactuary. For plants, we could just plant more plants! For minerals, we could save it by reusing raw materials from wasted automobiles. For fuel, we      could save it by using more natural energy like solar energy! And last but not least, for fresh water, we could save more fresh water by taking a shower instead of a bath!!!]]> 2017-12-30 07:15:09 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218175974 cchan11 https://padlet.com/cchan11/9eo6sdxfb1/wish/218176464 Around 6 million years ago, there was an increase of climate variability, this was known as the general trend. And also, the climate was unsteady during the past, so our ancestors need to adapt for better survive. Scientist also found out that as the time past, our ancestors' brains have gradually increased in size because of a dramatic climate change, so larger and more complex brains let us interact with each other and create more things to  better survive]]> 2017-12-30 07:50:50 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218176464 cchan11 https://padlet.com/cchan11/9eo6sdxfb1/wish/218190154 2017-12-30 15:55:53 UTC https://padlet.com/cchan11/9eo6sdxfb1/wish/218190154
