🌊 El Niño & La Niña
This climate pattern occurs when unusually warm surface water develops in the central and eastern tropical Pacific Ocean.
What is El Niño?
All of life on Earth exists in
What is The Biosphere?
Which ecosystem would generally have greater biodiversity?
A: An ecosystem containing 10 species
B: An ecosystem containing 100 species
What is B. an ecosystem with 100 species?
A forest receives less rainfall for several months. Is rainfall a biotic or abiotic factor?
What is an abiotic factor?
Which process describes water moving through evaporation, condensation, and precipitation.
What is the Hydrologic Cycle or Water Cycle
This climate pattern is characterized by unusually cool surface waters in the central and eastern tropical Pacific Ocean
What is La Niña?
A scientist studies deer, wolves, trees, birds, insects, and fungi living in the same forest but does not consider the soil, water, or temperature. What level is being studied?
What is a community?
A farmer grows one variety of corn across thousands of acres. What type of biodiversity is especially limited by having very little genetic variation among the crop plants?
Which aquatic ecosystem would most likely be affected by both river water and ocean water?
What is an Estuary?
What is the impact of burning fossil fuels on the environment?
What is contributes to global warming by increasing carbon dioxide levels in the atmosphere
Both El Nino and La Nina have this in common
What is Influence rainy / dry weather world wide
Ecologists study the interactions of organisms at five different levels. Which best places the levels from smallest to largest?
What is? B. organism→ population→ community→ ecosystem→ biome
What is an increase in atmospheric carbon dioxide
Which observation best shows that matter cycles through an ecosystem?
What is Carbon Atoms move between organisms and the atmosphere
What is an autotroph?
What is an organism that can make it's own food/energy
During El Nino, what kind of winter would be expected in the Southern United States?
Cooler and wetter than usual
A disease kills many rabbits in an ecosystem. Predict two possible effects this could have on other organisms in the ecosystem.
What is Predators that eat rabbits may decrease or
Plants eaten by rabbits may increase?
A forest loses a keystone species but still contains many other species. Which prediction is most resonable?
What is Major ecosystem changes may occur because the keystone species had a disproportionate effect.
A coastal plant has Salt-removing structures on its leaves. Which physical condition most likely led to this adaptation?
What is High Soil Salinity?
A food chain begins with algae, and continues to shrimp → Small Fish → 🐙 Octopus → 🦈 Shark. which organism recieves energy directly from the producer?
What is The Shrimp
What causes La Nina?
What is cooling water in the Pacific Ocean off the coast of South America?
A new highway divides a large forest into several smaller sections. Explain how this could affect both biodiversity and populations living in the forest.
What is habitat fragmentation, which can isolate populations, reduce available habitat, limit movement and gene flow, and potentially decrease biodiversity?
An invasive species enters a lake and reduces the population of a native fish. Which additional evidence would best support the claim that biodiversity has been hardmed?
What is The lake now has fewer native species and less stable food-web relationships.
A pond receives extra phosphorus from fertilizer runoff. Which result is most likely?
What is Increased algal growth followed by lower oxygen levels.
Why wouldn't the entire food web necessarily collapse when the crayfish population decreases?
What is Because the organisms have multiple variety food sources or connections.
