topic one.
the three types of animals are?
producers, consumers, decomposers
what are the two categories living and non living things sorted into?
biotic and abiotic
what are the differences between weather and climate?
weather is the short-term condition of the atmosphere, it can change rapidly, it is what is happening right now. climate is long-term weather patterns and the average over many years at one place.
what is symbiosis?
any relationship or interaction between two dissimilar organisms
producers are?
living things that make their own food from the sun, water, and soil
what are biotic factors?
all of the livings things in an ecosystem
what are biomes?
a region of land with characteristic climate, soil, and organisms.
what are the three types of symbiosis?
mutualism, parasitism, commensalism
consumers are?
living things that do not make their own food. all animals are consumers because they get energy from eating food. a food chain usually includes multiple consumers.
what are abiotic factors?
all of the non living things in an ecosystem
what are the six biomes in north america?
tundra, boreal forest, temperate forest, tropical rainforest, grassland, desert
define mutualism
a symbiotic relationship from which both partners benefit
decomposers are?
living things that that get their energy by breaking down dead plants and animals.
give three examples of each: biotic and abiotic factors
answers vary
what are the three biospheres?
atmosphere, hydrosphere, lithosphere
define parasitism.
a symbiotic relationship from which one of the partners is harmed and the other benefits
name one from each category: producer, consumer, decomposer
varying answers.
what six things are all biotic factors able to do?
grow, move, use nutrients, reproduce, produce waste, require oxygen
describe each of the six biomes in north america
tundra: treeless regions found in the arctic and on the tops of mountains.
boreal forest: coniferous forests, mostly of pines, spruces and larches.
temperate forests: regions with high precipitation, humidity, and a variety of deciduous trees. decreasing temperatures and shortened daylight hours means decreased photosynthesis for plants.
tropical rainforests: hot, moist where it rains all year long. it is known for its dense canopies of vegetation that form three different layers.
grassland: open and continuous, fairly flat areas of land.
desert: typically bald, rocky, or sandy surfaces in deserts are dry and hold little moisture, quickly evaporating the already little rainfall they recieve.
define commensalism.
a symbiotic relationship from which one partner benefits and the other remains indifferent
