Types of Interactions
What's the term that defines an "interaction between two different species that use the SAME resources"?
Competition.
In the atmosphere, sulfur oxides from factories combine with water vapor to form sulfuric acid which then falls to the ground as ______________.
acid rain
What is climate?
Prevailing (long-term) weather conditions (temperature and rainfall) in an area.
Which biome has the most diversity and rainfall?
Tropical Rainforest
Rocks and water are what kind of factors?
Abiotic
How is predation different than parasitism?
In predation, one organism KILLS another for food. In parasitism, one organism benefits and one is harmed (not killed for food, generally they do not want to kill their "hosts").
What are two effects of acid rain on ecosystems?
- Acidic soil inhibits plant growth - affects crop yields.
- Runoff can kill/damage fish and their eggs.
- Damage structures/buildings.
Temperature and precipitation are generally determined by __________ and ____________.
Latitude and elevation.
Which biome is characterized by having the lowest amount of rainfall and nocturnal, burrowing animals?
Desert
What is a niche?
The unique set of resources used by a species and its interactions with other species. Its "job" and pattern of living in an ecosystem.
What is commensalism and give an example.
Interaction where one species benefits and the other is neither harmed/helped.
Examples: Whales/Barnacles, Trees/Orchids, Sharks/Remora
The greenhouse effect is increasing on Earth because of greenhouse gases trapping more heat in the atmosphere. Name 2 greenhouse gases.
Water vapor, carbon dioxide, methane, nitrous oxide.
Temperature and moisture (increase or decrease) as you move farther away from the equator.
Decrease
Which biome has high temperatures and a 6 month dry/6 month wet season?
Savanna
What is eutrophication?
The algal bloom that is caused by an excess of nitrogen and phosphorous. Depletes oxygen from the aquatic ecosystem.
Define mutualism and give me an example.
Interaction where both species benefit or help each other. Examples: Clownfish/Sea Anemone, Humans/Pets, Bees/Flowers
Describe 3 effects of climate change.
Melting polar ice caps, rising sea levels, stronger hurricanes, increase in heat waves, droughts, wildfires, etc.
Temperature and moisture (increase or decrease) as you move UP in elevation.
Decrease
Which biome is characterized by permafrost, or permanently frozen soil?
Tundra
Give an example of overharvesting.
Answers may vary.
What are the 5 different ways that different members in a community can interact?
1. Predation
2. Competition
3. Mutualism
4. Commensalism
5. Parasitism
What are species that are at risk of becoming extinct in their natural habitat called?
Endangered Species
Compare the temperature and rainfall at the equator to the North/South Poles?
The equator has HIGHER temperatures and MORE rainfall. The poles have LOWER temperatures and LESS rainfall.
Which biome is characterized by long cold winters, short cool summers, and coniferous trees?
Taiga (Boreal Forest)
Name an invasive species and its negative effect.
Answers vary.
