what's the difference between biotic and abiotic?
biotic - living
abiotic - non-living
Give an example of predator and prey
lion and gazelle
shark and seal
where are the consumers on an energy pyramid?
They are every level except the bottom producer - they are living things that have to hunt or gather to get their energy
What are the building blocks of life?
cells
Give an example of a limiting factor
space, food source, water, disease, predators, etc
What's the difference between herbivore and carnivore?
explain what competition means
when two animals are fighting for the same resource. (fighting for food, space, water, etc)
What is the primary difference between a food web and a food chain?
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. A web shows the energy flow of an ecosystem.
When cells are combined - they form what?
tissue
Fill in the blank: Populations cannot grow without stopping because there are outside factors that will limit it. The largest population that an environment can support is the______________.
carrying capacity
Define: Ecosystem
Living and non-living things working together in a specific location
What type of Symbiosis is this:
Tapeworms are flatworms that are found attached to the insides of the intestines of animals such as cows, pigs, etc.. They feed on the host's partly digested food, depriving it of the nutrients
Parasitism
What is a food web?
A food web shows what organisms eat and how energy moves in an ecosystem.
name the 6 characteristics of life
made of cells
have DNA
develop over time
respond to change
need energy
reproduce
What is a species?
A group of living things that share similar DNA
Define: Ecology
the study of home/earth - both living and nonliving -
What type of symbiosis is this:
Clownfish and sea anemone - Sea anemones have stinging cells that keep the fish safe, while the fish keep the anemones free of parasites.
Mutualism
In an energy pyramid - what represents the largest portion of organisms at the bottom level?
producers - grass/shrubs
What is missing in the 4 needs of all living things:
space, food, water, and ________
homeostasis
What is a group of populations (biotic) in one location called?
Community
The ability of all living things to keep themselves temperature regulated
What type of symbiosis is this:
The remora's relationship with its host is primarily for navigational ease, allowing it to enjoy transport without exerting much energy.
How do decomposers help ecosystems?
they eat the dead and decaying organisms - they clean up our earth and put the energy back into the producers level of the pyramid
Explain the relationship between a fish that thrives in cold water and the water temperature.
As the water temperature gets warmer, the fish population declines. As the temperature gets colder, the fish population grows. Arrows are inverted.
What are the 4 types of consumers?
omnivores, carnivores, herbivores and scavengers
