some of Cornell notes in spelling words in definition
how are living things connected?
all living things are connected to other living things through what can be described as the global ecosystem, with the foundation of this global ecosystem being microbes.
what is a limiting factor?
A limiting factor is a common limiting factor resources are environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem.
how do predator and prey interact?
A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
how do organisms get energy?
Producers are organisms that get their energy directly from the sun. All plants are producers. The chlorophyll in plant cells traps the sun's energy.
Explain how the meanings of the biotic factor and abiotic factor different?
Biotic and Abiotic Factors. An ecosystem is defined as any community of living and non-living things that work together. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem.
what is a biome?
A large naturally occurring community of flora and fauna.
what is a community?
A community is a group of people living in the same place or having a particular characteristic in common.
why do predators eat prey?
they eat prey because the prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
consumers eat other organisms why?
Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers. Animals and people who eat both animals and plants are called omnivores.
what factors can determine where a population can live?
Biotic and abiotic factors both determine that a population can live or not in a particular place. Abiotic factors include air, water, soil, minerals, temperature.
what is the biotic factor?
The biotic factor is a living thing like dogs and cats.
what is a producer?
a person, company, or country that makes, grows, or supplies goods or commodities for sale.
why does competition occur in communities?
Every individual in an ecosystem requires certain things to survive and to reproduce. They compete with members of their own species and members of other species that need the same things interspecific.
how do energy transfer among organism?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
describe how the cells in your body get energy and then use the energy?
1: Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy. This process is called 'cellular respiration'. 2: The process is happening in all the cells in our body. Oxygen is used to oxidize food, main oxidized food is sugar
what is an abiotic factor?
Abiotic factors are non-living things.
what is a consumer?
a person who purchases goods and services for personal use.
what are the types of symbiotic relationship?
energy flows through a food chain how?
Energy flows into an ecosystem as a result of the capture of solar energy by plants, and through a food chain and food web.
name two factors that can decrease population size?
Limiting factors are resources or other factors in the environment that can lower the population growth rate. Limiting factors include a low food supply and lack of space.
what is a food web?
A food web is a system of an interlocking and interdependent food chain.
what is a decomposer?
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
how does prey sometimes hide?
Prey animals often use camouflage to hide from predators. Camouflage is a way of hiding that allows an animal to blend in with its environment or otherwise go unnoticed by predators.
why are consumers called that?
Animals are called consumers. This is because they cannot make their own food, so they need to consumers eat plants and or animals.
what do the arrows mean in a food chain represent?
Food chains Figure below show the eating patterns in an ecosystem. The arrow points from the organism being eaten to the organism that eats it.
