In a food web, the arrow depicts what information?
direction of energy flow or energy transfer from one organism to the other
What type of relationship exists if a hawk and a snake both eat mice?
competition (for food)
This biome is the largest in the world and has long cold winters (Canada).
Taiga
Energy is tranferred from a produer to a consumer how?
When the consumer eats the producer or the primary consumer or secondary consumer. Through what it eats.
This biome has a wet and dry season, warm all year and has scattered clumps of trees.
Savanna
Food chain...grasses-insects-bird-snake-large bird. What would happen if all the insects died out?
The number of birds (what eats the insects) would decrease
Plants can grow all year round in which biome because they receive large amounts of precipitation?
Tropical Rainforest
What is the carrying capacity of an ecosystem?
The number of organisms that the ecosystem can support and all their needs will be met. The line on the graph where it levels out and stays straight.
What does symbiosis mean?
a long term relationship
The ultimate source of energy for all organisms is the?
sun
In this symbiotic relationship, one organism is harmed (the host) and the other benefits at the detriment of the other.
Parasitism (Example: tick that feeds on blood of animals)
Name 3 abiotic factors in the desert.
sand, sunlight, humidity, air, rocks
This biome allows for very little to no growth. Only lichen and moss can survive the harsh environment (cold desert)..
Tundra
This biome is characterized by humid, wet weather, near the equator and very biodiverse.
Tropical Rainforest
In a population graph...you can expect the population of predators to show an increase when the population of prey shows a ________________.
decrease (more predators to eat, less prey available and vise versa)
This biome is dry and very cold. The coldest in the world. The ground is permanently frozen.
Tundra
Why do large, top predators (tertiary consumers) need to eat more than a primary consumer?
The amount of energy they receive from what they eat is much less than that of a primary consumer.
If 2 organisms share a burrow to live in. Which type of relationship exists between them.
Mutualism
In what trophic level on the energy pyramid do you find a primary consumer?
the second
What is the difference between a habitat and niche?
Habitat is where the organism lives (gets water, food, shelter, space). Niche is the role the organism plays within their environment (producer, consumer).
Name a top predator that would be at the top of an energy pyramid.
Any large carnivore...hawk, coyote, wolf (Apex predator)
