Ecological Principles
These organisms eat primary consumers
What are secondary consumers?
caused my pollution, making ecosystems less supportive of the wildlife
What is habitat degradation?
3 main types of habitats
What are marine, freshwater, and terrestrial?
the northernmost habitat in the Arctic region
What is the tundra?
This habitat receives less than 10 inches of rain per year and is the driest in the world
What is a desert?
It is a relationship between two species in which both species benefit.
What is mutualism?
this type of habitat destruction is created by building housing in an are for more people moving into an area
What is urban sprawl?
Areas where shallow pools of water form due to poor drainage of the land, and act as a transition area between water and land, they are important for filtering water
What are wetlands?
This is the only habitat that has all four seasons, is found at the mid-latitudes, and has trees
What is a deciduous forest?
home to dense, lush vegetation (evergreen trees, vines, ferns, mosses)
What are tropical rainforests?
Groups of organisms of the SAME SPECIES
What is a population?
Vegetation, Wetlands, Food, Wood
What are habitat benefits for people?
This place begins at the coastline and extends to the end of the continental shelf, supporting diverse life
What is the neritic zone?
also called a boreal forest and dominated by coniferous trees
What is the Taiga?
large flat plains dominated by various species of grasses
What are grasslands?
when an area of land that was once fertile no longer grows anything is and becomes very dry
What is desertification?
non-material benefits such as tourism, recreation, and beauty
What are cultural services?
Layer of the ocean that receives the most light - photosynthesis happens here
What is the epipelagic zone?
BONUS: these have clay soil as a substrate, which does not allow water to seep into the ground, making them very acidic with very little oxygen in the water
What are bogs?
This is why grasslands don't have trees
What is it doesn't rain enough?
This organism performs photosynthesis, but is NOT a plant
What is algae?
What are supporting services?
These are algae that make up the primary producers of the ocean; they produce 50% of the oxygen on Earth
What are phytoplankton?
This is described as soil that is frozen most of the year and can't support much life
What is permafrost?
adaptive characteristics of plants in deserts
What are shallow, widespread roots?
