Ecosystem and population
What is an ecosystem?
All the living things in a given area physical factors of the nonliving environment
What causes differences in biomes
It is due to the differences in abiotic factors
How are terrestrial biomes defined
A biome where there is a similar climate that includes similar communities of plants and animals.
Is volvox a producer, consumer or both?
Producer
What do the arrows pointing to the next organism mean?
It shows where the energy is transferring too.
How is a population different from a community?
A population is a group of organisms that belong to the same species bot a community is all the different species that live in an area together and interact
Name 3 factors that can be used to describe habitats
Average amount of sunlight received per day, The range of annual temperatures, and average yearly rainfall
Where is biodiversity the highest
Near the equator
What class(or groups) is Elodea in?
Plant (waterweed)
What does the top and bottom of the food web represent
The bottom represents primary producers while the top represents apex/dominant predators.
What is predation?
This is another mechanism in which species can interact with each other and when a predator organism feeds on another living organism.
What sort of adaptations do prey have for avoiding predators?
By avoiding detection by using camouflage or using micramy which mimics another animal's behavior.
Give 4 examples of terrestrial biomes
Tundra, taiga, tropical rainforest, and desert
How does Daphnia get energy or food?
By eating algae and bacteria
What part of photosynthesis creates energy?
The light dependent reactions create and capture sunlight for energy
What has to be true about available resources for competition to exist?
That it must be limited relative to the number of organisms that need it.
Can two species share the same niche? Why or Why not?
No, because they can have 2 similar species of niche overlap but there must be distinct differences between 2 niche
What are aquatic biomes defined by what factors?
The amount of salt that is in the water
Is euglena unicellular, colonial, or multicellular?
Unicellular
How do producers in the aphotic zone differ from those in the photic zone?
In a aphotic zone since then do not have enough sunlight they have to produce or make food by breaking down chemical compounds
What is the competitive exclusion principal?
The principle of ecology stating that 2 different species cannot occupy the same niche in the same place for very long
What influence does soil quality have on different biomes
Different plants will be able to be in/ occupy different biomes based on the soil quality.
Distinguish between freshwater and marine biomes
Freshwater biomes have less than 1% of salt in the body of water,but the marine biomes are salt dominated when it comes to characteristics.
List 3 organisms who decompose or are decomposers.
