How does an invasive species affect an ecosystem?

• The invasive species interacts with all of the living organisms in a non-competitive way
• The invasive species travels between multiple different ecosystems or habitats to find food
• The invasisve species solely depends on birds for its food supply
• The invasisve species can disrupt biodiversity and food webs by competing with or harming species native to that ecosystem

Invasive species are�

• organisms that disrupt the biodiversity and food webs by competing or harming the species native to that ecosystem
• organisms that help the biodiversity and food webs by competing or harming the species native to that ecosystem
• organisms that are native to an area and live off of weaker organisms
• organisms that disrupt the biodiversity by living in the same area as another species

Why is biodiversity important in fighting disease in food crops?

• It prevents one disease from wiping out an entire food crop.
• It prevents habitat loss of native species.
• It provides different foods for different populations.
• It prevents fungal disease from wiping out corn crops.
