Spheres of Earth
This sphere includes all of the Earth's water, such as oceans, rivers, and lakes.
What is the hydrosphere
These are non-living components of an environment, such as temperature and soil.
What are abiotic factors
This type of symbiotic relationship benefits both organisms involved.
What is mutualism
In a food chain, this organism typically starts the chain by producing its own food through photosynthesis.
What is a producer
At this trophic level, organisms are primary producers, such as plants and algae.
What is the first trophic level
This sphere encompasses all the living organisms on Earth, including plants, animals, and microorganisms.
What is the biosphere
This term refers to the living components of an ecosystem, like plants, animals, and bacteria.
What are biotic factors
In this symbiotic relationship, one organism benefits while the other is neither helped nor harmed.
What is commensalism
This term describes a network of interconnected food chains within an ecosystem.
What is a food web
These organisms occupy the second trophic level and primarily consume producers
What are primary consumers
This sphere consists of the solid outer shell of the Earth, including the crust and upper mantle.
What is the lithosphere
Abiotic factors like sunlight and soil composition influence these biotic factors.
What are living organisms
This relationship occurs when one organism benefits at the expense of the other.
What is parasitism
This level of a food chain includes organisms that consume primary producers
What are primary consumers
This level is composed of organisms that eat primary consumers
What is the secondary consumer level
This sphere contains all the gases surrounding the Earth, including oxygen, nitrogen, and carbon dioxide.
What is the atmosphere
A desert environment’s high temperature and low rainfall are examples of these factors affecting its biotic community.
What are abiotic factors
The relationship between bees and flowers, where bees get nectar and flowers get pollinated, is an example of this type of relationship
What is mutualism
The arrow in a food chain or food web represents this concept, indicating the direction of energy flow
What is energy flow
In this level of the energy pyramid, apex predators are typically found, having the least amount of energy available
What is the top (or fourth) trophic level
Rain carries soil into a nearby pond. This is an interaction between which two “spheres” of the earth?
the Geosphere & hydrosphere
The presence of predators, competitors, and prey are examples of these factors in an ecosystem.
What are biotic factors
The relationship between a tapeworm and its host is an example of this type of symbiosis
What is parasitism
In a food web, this is the term for organisms that consume both plants and animals
What is an omnivore
How much chemical energy is transferred from the producer level to the secondary consumer level in a food chain?
what is 10%
