Aside from killing native species, what other negative issue might an invasive species present?
Aside from killing native species, an invasive species might also disrupt natural ecosystems and food webs, introduce diseases or parasites, alter the physical characteristics of habitats, impede human activities such as agriculture or fishing, reduce biodiversity and genetic diversity, increase the risk of wildfires or floods, and create economic costs for eradication or control efforts.
no, the options are
They might avoid interacting with other organisms.
They might introduce other organisms, like viruses and bacteria.
They might increase the diversity of native species.
They might provide economic benefit.
They might introduce other organisms, like viruses and bacteria.
What happens after coral is bleached?
The coral produces peroxides.
The coral is susceptible to starvation.
The coral dies immediately.
The coral releases algae into the ocean
After coral is bleached, the coral is susceptible to starvation. Coral bleaching occurs when the coral expels the algae that lives in its tissues, causing it to turn white. These algae are crucial for providing the coral with energy through photosynthesis. Without the algae, the coral becomes weaker and more susceptible to disease and starvation. If the bleaching event is severe and prolonged, the coral may die.

The Florissant Fossil Beds in Colorado are home to several massive redwood stumps that were subjected to a special kind of fossilization millions of years ago. These fossilized stumps are most likely providing a service related to tourism, as they serve as a fascinating and valuable educational and recreational resource for visitors to the area interested in natural history and geology.
Marine biologist Dr. James Estes researched sea otters and their habitats in the Aleutian Islands of the North Pacific Ocean. Sea otters feed on animals such as crabs and urchins. Islands with sea otters contained a lot of kelp, a seaweed that is an important food source for fish and other sea animals. However, Islands without otters had large populations of urchins but no kelp since sea urchins feed on this seaweed. Since sea otters are able to control the population of urchins, this allows for kelp to freely grow in those areas. Given this information, what term best describes the otter in the Aleutian Islands ecosystem?(1 point)

The term that best describes the otter in the Aleutian Islands ecosystem is "keystone species." Keystone species are species that have a disproportionate effect on their environment despite their comparatively low biomass or abundance, and the sea otter is an example of a keystone species. By feeding on sea urchins, sea otters help control their population, which in turn allows kelp and other aquatic plants to thrive, providing food and habitat for numerous other species in the ecosystem.
Your friend John is having trouble with his compost bin. The material in his compost pile doesn’t seem to be decomposing well. You take a sample of the pile and check for the presence of microorganisms under the microscope. You see that there are indeed microorganisms; however, they don’t appear to be growing very fast. John says that he regularly mixes his compost pile to expose it to oxygen but has noticed the pile feels cold. What is the most likely explanation for this problem?(1 point)
