Fungi & Pathogens
This originated in Asia. It infects the amphibians and they often experience cardiac arrest due to electrolyte imbalance. What is it?
Batrochochytrium dendrobatidis (Bd)
What happens when a predator is removed from the ecosystem?
Prey population increase and Plant population decline
what is a ecosystem
this term describes all the living and nonliving things that interact in a specific environment.
Where do producers get their energy from?
The sun
genetic Diversity definiton
Variety of DNA within a single species or population
It spreads through wind-dispersed spores, infects through bark wounds, and thrives in temperate forest climates. What is it?
Cryphonectria parasitica
What three organisms does a trophic cascade involve
A producer, A primary consumer, A secondary consumer
Why is biodiversity important for ecosystem stability?
allowing ecosystems to recover faster from disasters like disease, climate change, and drought
What is the primary role of a decomposer in a food web?
They recycle nutrients back into the soil by feeding on dead materials.
Species Diversity definition
Variety or abundance of species in area
This can destroy up to 70% of wheat yield in outbreaks and have a rapid evolutionary mutation. What is it?
Puccinia graminis
What effect did the reintroduction of wolves have on the Elk population?
It caused Elk population to decrease
What are abiotic factors?
The non-living parts of an environment like sunlight, water, and soil
What happens if one link in a food web dies off?
Other parts of the web might die off, but unlike a simple chain, organisms in a web can often find alternative food sources to survive.
why is biodiversity important for ecosystem stability
It increases redundancy of roles
Kingdom: Fungi
Phylum: Zoopagomycota
Parasitic/pathogenic classification: Obligate insect parasite
What is it?
Entomophthora muscae
What is a Niche?
The role or job a species has in its ecosystem
Why do food Webs usually have more producers than consumers?
Energy is lost as heat at each transfer, meaning less energy is available to support higher trophic levels.
Explain why biodiversity loss increases ecosystem vulnerability?
Biodiversity loss increase ecosystem vulnerability due to some species not having traits to accumulate to the environments.
Ecosystem impact: have a loss of keystone tree species and altered forest canopy structure. What is it?
Hymenoscyphus fraxineus
What is resilience?
The rate at which an ecosystem returns to its original state after a disturbance.
What is the main difference between a food chain and a food web chain?
A food chain is single a pathway of energy, while a food web consists of many interconnected food chains showing all organisms an animal eats.
