Food Web
What do you call a Specie that has lots of connections in a Food Web
A Specie that is connected to many others
What helps hold the system together?
Keystone Species
When changes occur at the level of the top predator what happens
Causes a Trophic Cascade throughout the ecosystem
How is Human Impact on the Ecosystem
Humans can Harm the Ecosystems by Cutting Down Trees, Polluting air and water, Taking away to many animals and plant, Build things that destroy habitats
Why are predators important in ecosystems?
Prey population decreases
What happens to the Food Web when a Keystone Specie is removed
The Food Web can get messed up or fall apart and get destroyed
What could happen if a Specie of keystone disappear?
Others as in Populations could grow or decrease too much
The reduction in wolves leads to.....
an Increase in Elk. A Specie that Do eat trees
What happens when habitats are destroyed?
Animals will lose their homes as in they are going to lose their habitats
Why do predator and prey populations often rise and fall over time?
They depend on each other for survival
What's the main source of energy in most food webs
The Sun
True or False : A keystone species has a small impact on the ecosystem
False
What Effect in the ecosystem that leads to huge changes in the whole Trophic Pyramid.
A Ripple effect
What is human Impact?
How Human actions can change ecosystems
What is ways prey animals protect themselves from predators?
Camouflage, Hiding, or Running Away
What is a Food Web
Food chains that are connected in a group
Why Keystone Species are NOT formally acknowledged, and scientists may debate which plants or animals in a particular ecosystem deserve the title
Ecosystems are Different researchers focused on different evidence.
Why are trees NOT DIRECTLY AFFECTED by Wolves
Trees get affected by deers acting differently
How can humans help the ecosystem?
Recycling, Protecting Habitats, or Reducing Pollution
If there are too many prey animals in the ecosystem what might happen?
They could eat too many plants
How are Food Webs more helpful than food chains?
Food Webs can affect many other organisms
Why are keystone predators are Important?
Keystone predators control prey populations
What happens to the ecosystem when predators keep herbivore numbers under control?
Plants and other species stay more balanced
What happens to ecosystems when too many resources are used?
What do Predators help the populations of prey species
Affects the Quanity of plants and animals further along the food web
