Biomes
If you discovered a place that is:
Very cold
Treeless
Has little precipitation.
What biome am I?
Tundra.
______ is the most important extinction threat for most terrestrial species.
Habitat Loss
This biome typically has the highest biodiversity due to abundant sunlight and rainfall.
Name 1 abiotic factor found in marine ecosystems.
Rocks, water, sunlight, temperature, etc
Because the giant panda eats mostly bamboo and depends on bamboo forests for survival (primary in China), it is classified as this type of species.
(think beyond herbivore classification)
Specialist.
What is the major difference between tropical rainforests and temperate rainforests?
Tropical rainforests are warmer, while temperate rainforests are cooler
What are the 3 kinds of biodiversity:
genetic, species, and ecological.
The largest dry desert in the world.
Sahara Desert
These marine ecosystems are famous for their high biological productivity and incredible diversity of colorful organisms.
Coral Reefs
The cleaner fish eats the leftover food out of the moray eel's teeth. The fish gets a meal while the eel's teeth get cleaned. What symbiotic relationship is shown between the moray eel and cleaner fish?
Mutualism
If you discovered a place that has very little precipitation, extreme temperatures, and plants and animals adapted to conserve water, you would most likely be in this biome.
Desert
What is the difference between marshes and swamps?
Marshes: Wetlands without trees
Swamps: Wetlands with trees
Describe the term adaptation. Give an example of an adaptation in nature.
Adaptations are traits that helps an organism survive and reproduce in its environment.
Example: camo, fur, scales
What is the tiny, free-floating photosynthetic algae that often supports a marine food web
Phytoplankton
Mosquitoes bite humans and suck their blood to get food. In return, the human is itchy and can even contract a disease. What type of symbiosis is shown between the mosquito and human?
Parasitism
This biome is located near the equator, has warm temperatures year-round, and receives large amounts of rainfall, leading to the highest biodiversity on Earth.
Tropical Rainforest
What is the solution to overgrazing?
Then describe how it works.
The solution to overgrazing is rotational grazing.
Rotational Grazing is when you enclose livestock in a small area for a short time to force them to eat vegetation evenly.
Biome type can be predicted based on:
Temperature and precipitation
Estuaries are bays where rivers empty into the sea, mixing ___ water with __ water.
Fresh Water, Salt Water
Describe the difference between a community and ecosystem.
A community = only living things in an area (different species)
An ecosystem = living things + nonliving environmental factors interacting together.
1. Define invasive species
2. Why are invasive species especially harmful to ecosystems and biomes?
Invasive species: species that does not naturally occur there.
they lack natural predators, introduce competition, disrupt food webs, etc
When a large natural habitat is broken into smaller, isolated patches by roads, cities, or farming, this process occurs and often leads to reduced biodiversity.
Habitat Fragmentation
The wolf in Yellowstone National Park helps control elk populations, which in turn allows plants and other animals to thrive.
A species like this, which has a disproportionately large effect on its ecosystem, is called what?
Keystone Species
Name three organisms you might find in a marine ecosystem, and describe how they could be connected in a food web (what eats what)
answers will vary.
Phytoplankton (producers) are eaten by small fish, and the small fish are eaten by sharks. This shows how energy moves from producers to consumers and then to top predators in a marine ecosystem.
Coal, oil, and natural gas are examples of this type of energy resource that cannot be replaced quickly.
Nonrenewable resource or Fossil Fuel
