These include the atmosphere, lithosphere, hydrosphere, and the biosphere. The biosphere is where life on earth exists, and there can be microorganisms up to several kilometres beneath the earths surface! My favourite part about this section is the Gaia hypothesis. It states that the earth acts as a living organism as it maintains a sustainable environment and responds to changes in the environment. I love this theory because I think it's just a beautiful way to look at the world. ]]> 2021-05-30 18:48:43 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1571896657 852524 https://padlet.com/852524/l1zmam01j14ipybw/wish/1571896883 2021-05-30 18:48:56 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1571896883 852524 https://padlet.com/852524/l1zmam01j14ipybw/wish/1571905164 This section we learn about ecosystems. An ecosystem contains biotic and abiotic factors, which interact with each other and the environment. The different parts of an ecosystem can be broken down into parts. First, a single organism (a deer). Then a population of deer. Then a community with different species, including food and predators. Then an ecosystem, which includes its abiotic features. ]]> 2021-05-30 18:56:31 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1571905164 852524 https://padlet.com/852524/l1zmam01j14ipybw/wish/1571905630 All organisms need energy to survive. Most energy on the planet comes from the sun. One way organisms get energy is photosynthesis. This is a process which turns light energy into sugars, which are used to feed a plant, and it also helps with nutrition, reproduction and growth. There is also cellular respiration, which is a process that turns sugars and oxygen into energy. ]]> 2021-05-30 18:56:40 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1571905630 852524 https://padlet.com/852524/l1zmam01j14ipybw/wish/1571906313 This section we learn about each place that organisms have in an ecosystem. This "role" that an organism plays is called an ecological niche. This identifies how it behaves, what food it eats and much more. Some categories of consumers include herbivore, omnivore, carnivore, and scavenger. One way to understand this complex system is a food chain or a food web. It just shows who eats who in an ecosystem. For example, the grass gives energy to the rabbit, which gives energy to the hawk, which gives energy to the owl. It helps you better understand by laying out the system in a simple way.]]> 2021-05-30 18:56:49 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1571906313 852524 https://padlet.com/852524/l1zmam01j14ipybw/wish/1571928962 1) Mass is proportional to gravity and gravity is necessary to hold up the atmosphere.
2) The atmosphere protects earth by shielding us from radiation and keeping the earth warm. 
5) The biosphere is very thin. There are many conditions needed for any life to be able to survive.
7) What interested me most was the "Gaia Hypothesis" that earth is like a living organism. Everything on earth is connected, living and nonliving and it all works together in a way that forms its own organism.]]> 2021-05-30 19:19:23 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1571928962 852524 https://padlet.com/852524/l1zmam01j14ipybw/wish/1572030579 1) Biotic: bacteria, dead leaves, mosquitoes, milk, hair, plastic and a snail shell. Abiotic: temperature, wind, sunlight, sand and ice.
2) Communities include abiotic features, since they are formed when abiotic and biotic features interact.
3) A backyard, tree, schoolyard, vase of flowers, potted plant, and the digestive system are all ecosystems because there are both abiotic and biotic features interacting.
4) This is false, humans impact everything around us, including abiotic features. For example, pollution effects not only animals and other living things but also the air and land. 
5) A large city would be a community, not a population.]]> 2021-05-30 21:02:31 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1572030579 852524 https://padlet.com/852524/l1zmam01j14ipybw/wish/1572196653 1) 70 percent of solar energy is absorbed by the atmosphere and hydrosphere, and a small percentage of this energy is absorbed by autotrophs for photosynthesis. The energy is used for activities such as growth and movement.
3) Plants have chlorophyll which helps them with photosynthesis. That produces the energy they need.
4) They are also used for fuelling growth and reproduction. They are also used for building proteins.
5) Photosynthesis turn oxygen into sugars. Cellular respiration is when oxygen and sugars are turned to water and carbon dioxide.
6) Producers use photosynthesis and cellular respiration while consumers undergo cellular respiration only.
8) Prior to reading this I would think oxygen is more important. And while I still think it is very important, plants provide so much more, aside from food also help with distributing nutrients in the soil.
11) Photosynthesis can only be performed during the day because it requires the heat and light from the sun, cellular respiration does not.

Humans are in a niche with other top predators. Another example of how organisms play a role: grass provides food for deer, but in order for grass to not diminish completely, wolves will eat the deer.
3) It affects everything in the ecosystem. If carnivores are gone, then the population of herbivores runs wild, and plants will die.
4) The energy turns into metabolic heat as the next tropic level only gets 10%.
7) They all live in different regions of earth, and although they have similar ecological niches they are not seen together.
8) If the red fox was taken out then the rabbit, mouse and squirrel population would grow, which would eventually eliminate the plants they feed on, which in turn would wipe out the entire ecosystem.]]> 2021-05-31 15:06:36 UTC https://padlet.com/852524/l1zmam01j14ipybw/wish/1573824213
