Biomes
What is a biome?
a large area defined by climate conditions, and as a result, animals and plants with specific adaptations to that climate.
What is an ecosystem?
A localized area of living things and abiotic factors.
True or False. Sunlight is a living thing.
False
What is a habitat?
Where an organisms lives. Includes abiotic and biotic factors.
True or False. Each organism in an ecosystem interacts with other organisms as it goes about its daily activities.
True
What is a biotic factor?
Living components
What living systems are biomes made up of?
Ecosystems or habitats. Either answer.
What factors are included in an ecosystem?
Abiotic and biotic factors
True or False. Air is not a living thing.
True.
What is a niche?
What are some limited resources that two organisms may compete for?
Food, water, shelter, mates/reproduction
What is an abiotic factor?
nonliving components
What biome is dry with little rain?
Desert
What living systems are ecosystems made up of?
Communities and populations
Name at least two of the five characteristics of living things (traditional definition)?
made of one or more cells
reproduce on its own
grow and change over time
require an energy source to survive
respond to changes in environment
What is the niche of a shark?
Predator. Keeps population off fish in balance.
True or False. A capybara eating grass is an example of a predator-prey relationship.
True
What is predation?
Process by which one organism, the predator, captures and feeds upon another organism, the prey - transfer of energy in the food chain.
What biome is humid, rainy, warm, and filled with biodiversity?
Rainforest
What is a population?
A group of the same species living in the same area
What is the alternative definition of a living thing?
What is the niche of a cactus?
Provides shelter, water, and food source in the desert for other animals.
True or False. All relationships between two or more organisms of different species always results in one benefitting and the other being harmed.
False.
What is competition?
Two organisms compete for the same limited resource.
What biome is aquatic and with salt water?
Marine
What mechanism do ecosystems have in order to maintain balance?
Provide a Claim (statement), Evidence (which definition of living you use), and Reasoning (how viruses fit into that definition) that viruses are not living.
Viruses are not living. The traditional definition of life is that it includes one or more cells, reproduces on its own, grows/develops, and requires an energy source. Viruses do not require an energy source to survive, they do not grow or develop, and they cannot reproduce on their own.
True or False. A niche is species-specific.
True.
Name the three types of symbiotic relationships.
mutualism, commensalism, parasitism
What is mutualism?
Define and give an example.
Both species benefit from the relationship.
Shrimp cleans the mouth of a fish. Shrimp gets food, fish keeps mouth clean from harmful infections.
Name the 9 major biomes.
Tundra, Taiga, Rainforest, Temperate Forests, desert, savanna, marine, freshwater, grassland
What is the main difference between a biome and an ecosystem?
Ecosystem is a localized area/community of living organisms and abiotic factors, whereas a biome is a much larger region.
Provide a Claim (statement), Evidence (which definition of living you use), and Reasoning (how viruses fit into that definition) that viruses are a living thing.
Viruses are a living thing. Living things can be defined as an emergent property of nonliving components Viruses are made up of nonliving things that together form an emergent property of reproducing within a host, jumping from host to host, and harming a host.
Viruses are a living thing. The traditional definition of living things includes that it responds to changes in environment. Viruses do respond to changes in their environment by evolving and adapting genetically to better survive.
What three major factors make up a species' niche?
Food sources, abiotic conditions, and behaviors.
What is the difference between commensalism and parasitism? Compare and contrast the two.
In commensalism, one organism benefits, like in parasitism. But unlike parasitism, the other organism is unharmed in commensalism, whereas in parasitism, the other organism is harmed.
What is commensalism?
Define and provide example.
Birds nest in trees. Trees don't benefit, but are also not harmed. Bird gets a shelter for its nest.
