What are the 4 main types of consumers?
Herbivores, Carnivores, Omnivores, and scavengers
This process in the water cycle happens when liquid water changes into water vapor.
Evaporation
A biome is a large region on Earth that has a particular climate and these two living factors.
Plants and animals
What are the two main types of aquatic ecosystems.
What are freshwater ecosystems and marine ecosystems
This word means the movement of organisms from one place to another.
dispersal
This type of organism can make its own food, usually using sunlight.
A Producer
In the carbon cycle, plants take in this gas from the atmosphere to make sugar during photosynthesis.
Carbon Dioxide
This biome is extremely cold, has frozen ground called permafrost, and very short growing seasons.
A tundra
Streams and rivers are freshwater ecosystems where water is always doing this…
Flowing/ Moving
This process explains how continents slowly move over time and once formed one large landmass called Pangaea.
continental drift (or plate tectonics)
This shows one path of how energy moves from one organism to another.
A food chain
Most organisms cannot use nitrogen gas directly, so this process carried out by bacteria changes nitrogen into a usable form in the soil.
nitrogen fixation
These trees keep their needle-like leaves year-round and are common in the boreal forest.
What are coniferous trees
This factor limits how deep most plants can grow in aquatic ecosystems.
What is sunlight?
Seeds that stick to animal fur or clothing are using this type of dispersal.
Dispersal by other living things (or hitchhiking on animals)
Only about ________% of energy is passed on from one level of the energy pyramid to another.
10%
Cutting down forests increases carbon dioxide in the atmosphere because it reduces this important process done by plants.
Photosynthesis
This rainforest type gets more than 300 centimeters of rain each year and is located near the equator.
a tropical rain forest
This ocean zone is the shallow area near the shore where sunlight reaches the bottom and many organisms live.
What is the intertidal zone
Mountains, oceans, and canyons are examples of this factor that can prevent species from spreading.
physical barriers
Because most energy is lost as heat at each level, ecosystems usually cannot support many organisms at this trophic level.
the highest trophic level (third-level/top consumers)?
Water, carbon, and nitrogen cycles are all examples of this type of movement, where matter is reused and does not disappear from Earth.
Recycling of matter (or matter cycling through ecosystems)
Grasslands have few trees mainly because of these two environmental factors that prevent forests from growing.
low rainfall and frequent fires (or drought and fire
Many deep-ocean organisms have adaptations like glowing bodies or large mouths because of these two environmental conditions.
What are darkness and low food supply
When humans accidentally introduce species to new environments where they have no natural predators, this type of species can form.
an exotic (or invasive) species
