Ecosystems Study Jams Summary:
Abiotic and biotic factors work together make an ecosystem survive and flourish. Abiotic factors are non living things such as rain, sunlight, temperature, minerals and soil. Biotic factors are the living things such as plants, animals, and bacteria. Changes In Ecosystems Study Jams Summary: Nature and humans both cause changes to occur in an ecosystem. When new organisms gradually grow in an environment , it's called succession. Primary succession is when a new environment is formed, and it happens over a long period of time. Secondary succession is when an ecosystem has been wiped out and it regenerates itself; it occurs over a shorter period of time. Food Chain Study Jams Summary: Food chains are the feeding relationships between organisms in an ecosystem. The food chain/pyramid consists of herbivores, carnivores, and decomposers. Producers are the plants in an ecosystem; they get their energy from the sun. Herbivores (Level 1 Consumers) are the animals that eat the plants to get their energy. Carnivores (Level 2 Consumers) are the animals that eat herbivores to get their energy. Carnivore (Level 3 Consumers) are the animals that eat other carnivores to get their energy. Decomposers are the bacteria that eat dead animals and transform them into minerals for the soil. Food Webs Study Jams Summary: A food web shows the complex feeding relationship between organisms in an ecosystem. A food web has many organisms from each level: decomposers, producers, herbivores, carnivores, and omnivores. Symbiosis Study Jams Summary: Symbiosis is a relationship between two organisms. The three types of symbiosis is parasitism, mutualism, and commensalism. In parasitism, one organism is benefits while the other is getting hurt. In mutualism, both organisms benefit. In commensalism, one organism is benefitting, yet the other isn't harmed. Biomes Study Jams Summary: There's 6 different biomes on earth, and each biome has a different climate which is suitable for many different plants and animals and their habitats. Population Growth Study Jams Summary: Populations are affected by many different things. Every species has a role to play in the food web; if one dies out, or goes extinct, the whole thing is disrupted. Limiting Factors are species that help limit the population of a certain organism, and an endangered species is a plant or animal that is in danger of becoming extinct. |

The variety of life in the world, a habitat, or an ecosystem. It allows predators to have a wider variety of prey to choose from. Post an image of an environment that has a lot of biodiversity. Where does the energy for all ecosystems originally come from? The sun. Why do all organisms in an ecosystem depend on producers? They're the originators of the energy pyramid, since they are the only ones able to get energy directly from the sun. How does a food web help show feeding relationships in an ecosystem? |
