Biotic factors of an ecosystem are:
Living Things
Which watery biome has the lowest concentration of salt?
Freshwater
The measure of total salt content dissolved in water.
Salinity
If you had a tape worm, what type of symbiotic relationship would that be?
Parasitism
Type of forest biome near the equator; receives a lot of rain; temperatures are warm all year.
Tropical Rain Forest
Sunlight is what type of factor
Abiotic factor
Which biome has 4 seasons?
Deciduous or Temperate Forest
What is the difference between a pond and a lake?
ponds are smaller where light reaches the bottom and lakes are bigger with no sunlight at the bottom
Which symbiotic relationship is it where one organism benefits and the other organism neither benefits or is harmed?
Commensalism
Forest biome with many different trees, mosses and ferns; most trees lose and regrow their leaves each year.
Temperate Forest
One characteristic feature of tundra is that only the surface thaws in the summer and refreezes in the winter, leaving a layer of permanently frozen subsoil. This characteristic is known as
Permafrost
Why are organisms so well-adapted to the conditions of the biomes in which they live?
Adaptation. They have slowly evolved to adapt to their environments.
The kind of wetland formed where saltwater and fresh water meet is called
Estuary
Flowers provide bees with nectar and pollen, which worker bees collect to feed their entire colonies. Bees provide flowers with the means to reproduce, by spreading pollen from flower to flower in a process called pollination. What type of symbiotic relationship is this?
Mutualism
Which biome contains large populations of grazing herbivores, few species of birds, and deep, rich soil?
Grassland
What similarity does a tundra and dessert have
low precipitation rates
What are the key features of the Tundra?
treeless, permafrost, cold dark winters
This biome contains mostly spruce trees and Douglas firs, which are both evergreen. The winters are long and cold and the summers are short and rainy. The soil is very rich. Moose and elk live here. This biome is classified as a
Taiga

shows many feeding relationships that are possible in an ecosystem
Which biome receives between 0 and 25 centimeters of precipitation each year, has a temperature range from -27 to 5 degrees Celsius, has frozen soil, and is home to hares, caribou, and wolves?
Tundra
What are the 5 basic components of an ecosystem to survive?
Producers
Consumers
Decomposers
Abiotic Factors
Biotic Factors
In what wetland would you expect to find NO trees
Marsh
What are the layers of a Rainforest?
4: emergent, canopy, understory, and floor
What is the definition of a population?
