Disruptive Events
This type of natural hazard refers to a lack of water in an area.
What is a drought?
This term describes a relationship in an ecosystem where both organisms benefit from each other.
What is mutualism?
This represents an organism that only eats meat.
What is a carnivore?
This is the type of organism that uses photosynthesis to make its own food.
What is a producer?
What is competition?
Positives of this disruptive event include clearing underbrush and giving space for new vegetation to grow in newly exposed soil.
What is a wildfire?
A relationship between a snake and a mouse would be described as this.
What is predation or predator-prey?
This process involves the breakdown of dead organisms to recycle nutrients back into the ecosystem.
What is decomposition?
This is the term for the transfer of energy from one organism to another through food chains.
What is energy transfer?
A shark and a remora fish have this type of relationship because the remora is being helped but the shark is not harmed or benefitted.
What is commensalism?
This happens when water overflows onto land that is normally dry and can cause mass destruction of property and habitats.
What are floods?
These are the three types symbiotic relationships that organisms can have.
+100 points for each one given.
What are mutualism, parasitism, and commensalism?
Sun > Grass > Deer > Wolf > Mushroom
This is what the wolf is considered in the food chain.
What is the secondary consumer/ apex predator?
A relationship where at least one organism benefits from the interaction.
What is symbiosis/a symbiotic relationship?
A scientist observes that both birds and snakes in the same ecosystem depend on the same mouse species as a food source. The relationship between the birds and the snakes is an example of this.
What is competition?
This type of disruptive event would be considered a biological disruptive event because the disruption is a biotic factor.
What is an invasive species?
This is the term that describes the relationship between two different species of organisms in an ecosystem, where one of them benefits from the interaction and the other suffers.
What is parasitism?
This can best be best described as an interlocking series of food chains that more accurately show how energy is transferred in an ecosystem.
What is a food web?
An ecosystem that maintains a consistent balance in population sizes and environmental conditions has this.
What is ecosystem stability?
Plankton > Krill > Mackerel > Tuna
This is the organism that eats the herbivore in this food web.
What is the Mackerel?
(Secondary Consumer)
The ability of an organism to adapt to changing environments and overcome challenges.
What is resilience?
This is the type of symbiotic relationship that is characterized by one organism benefiting while the other is neither helped nor harmed.
What is commensalism?
Sun > Grass > Mouse > Snake > Hawk
In the food chain, the mouse is a herbivore and also a...
What is a primary consumer?
The different types and species of biotic factors found in an ecosystem.
What is biodiversity?
The gypsy moth is an invasive species. The caterpillars of these moths eat the leaves of hardwood trees. Eating these leaves decreases the growth of the trees and may cause the trees to die. An increase of the gypsy moth will lead to this outcome for the trees.
What is a decrease in tree populations?
