Food Chains
a hierarchical series of organisms each dependent on the next as a source of food.
food chain
a change in one or more physical properties of matter without any change in chemical properties.
Physical Change
What is it called when wind breaks down rocks
Weathering
This biome, characterized by vast expanses of grasses and few trees, is home to grazing animals like bison and zebra. What is the name of this biome?
Grassland biome
In ecological succession, what term describes the initial colonization of barren land by pioneer species that can tolerate harsh conditions and often facilitate the establishment of other species?
Primary succession
organisms that make their own food
producer
a change of materials into another, new materials with different properties and one or more than one new substances are formed.
chemical change
When rock is moving and getting smoothed out
Erosion
This biome, found in polar regions, features extreme cold temperatures, minimal precipitation, and is characterized by a landscape of ice and snow. What is the name of this biome?
Tundra
What term describes the type of ecological succession that occurs on preexisting soil after a disturbance that leaves the soil intact, such as a fire or a severe storm?
Secondary succession
Where do all food chains get their energy originally from?
The Sun
Physical or Chemical: Bread dough being baked.
Chemical
When rock is stopped and dropped into a place
Deposition
This biome is characterized by its dense vegetation, high precipitation, and warm temperatures year-round. It is home to the greatest biodiversity on Earth. What is the name of this biome?
Tropical rainforest
What term refers to the final stage of ecological succession, characterized by a stable community of organisms that remains relatively unchanged unless disturbed by a significant event?
Climax community
series of interlinking food chains
food web
Jacob burned wood to make a campfire. After some time, all that was left was ash. What type of change is this?
Chemical
This geological process involves the transportation and deposition of sediment, leading to the formation of landforms such as deltas, sand dunes, and alluvial fans. What is the term for this process?
sedimentation
This biome, characterized by its vast, flat terrain covered in grasses, is often subject to seasonal flooding and is home to diverse wildlife such as elephants, giraffes, and lions. What is the name of this biome?
Savanna
What term describes the orderly and predictable process of change in the composition of species in a given area over time, typically following a disturbance?
Ecological succession
10% rule
Only 10% of the energy consumed from an organism is passed on.
Physical or Chemical: Trail Mix
Physical
What is sedimentation?
Colorado river
This biome is characterized by its cold temperatures, coniferous forests, and acidic soils. It is found in high latitudes and high altitudes. What is the name of this biome?
Taiga
What is the term for the process of ecological change in an ecosystem where new communities of organisms gradually replace one another?
Succession
