GRAPHS! In my Ecology class??
Which graph is shaped like a J? An exponential growth graph, or a logistic growth graph?
An exponential growth graph
Define Human Impact.
Human impact is the consequences of human actions
Define adaptations
Adaptations are things that organisms use to survive in their environment
Define biodiversity
Bio = life , diversity = difference.
Biodiversity is the difference of life
Define an ecosystem
An ecosystem is all of the biotic and abiotic factors in an area
What do we see on an exponential growth graph?
We see a population that has no limiting factors and keeps growing.
This term describes the practice of catching fish at a rate faster than they can reproduce, severely reducing marine populations.
Overfishing
List a structural adaptation
Mimicry or Camouflage
Non-native species in an ecosystem that often lead to the decline of native species, is known by this term.
Invasive species
Which biome is characterized by sand, hot temperatures, and cacti?
A desert
What do we see on a logistic growth graph?
We see a population that is limited by limiting factors and therefore, it reaches a carrying capacity
What is the term for when substances are introduced into the air, land, or water?
Pollution
List a behavioral adaptation
Hibernation or Migration
The wildebeest of the Savanna ate the dry grass that led to the rapid spread of forest fires. What happened as a result of that?
The biodiversity of the ecosystem increased as the lack of fire brought back habitats
An invasive species has entered a river! What impacts will it have on the native species?
The native species will decrease because of the presence of the invasive species
What is a carrying capacity?
Carrying capacity (K) is the maximum amount of organisms that an ecosystem can support
This term describes the process when natural habitats are destroyed, making them unable to support the species that live there.
Habitat Destruction
Hibernation and Migration are used for the same reasons, but hibernation involves sleeping and migration involves moving around
The burning of fossil fuels, deforestation, pollution, and rising levels of carbon dioxide have led to this
Climate change
This type of species has a disproportionately large effect on its ecosystem, and its removal can lead to significant changes.
Keystone species
What relationship do we see on a predator/prey graph?
A predator/prey graph shows that a growth in the prey population results in a growth in the predator population.
It also shows the opposite!
Human activities such as habitat destruction and pollution have accelerated this, the permanent disappearance of species.
Extinction
Compare and Contrast Mimicry and Camouflage
Mimicry and Camouflage are used for the same reason: to avoid predators. Mimicry is to look like a different organism, Camouflage is to blend in with the environment to hide from predators
An entire forest was chopped down. What impact will this have on the area's biodiversity?
It will completely destroy the biodiversity of the forest.
This term refers to the practice of assisting the recovery of ecosystems that have been damaged, degraded, or destroyed.
Ecological restoration
