For example, a dam is built to form a lake. The dam stops a predatory species of fish from getting upstream during mating season. Behind the dam, a species of minnow suddenly loses their natural predator, and their population explodes. In the spring, they feed on certain aquatic larvae and wipe them out. The larvae then do not hatch into a type of fly that feeds a particular species of bird during the birds' mating and nest building period. The birds die out or move elsewhere. The birds also fed on the fruits of a particular tree. The seeds of that tree cannot germinate until they have first passed thru the digestive system of the bird, which weakens the seed coat and triggers germination. That species of tree dies out. Another species takes over and fills in the vacated space. A particular insect feeds on this second species of tree, so their population explodes.
What else can I help you with?
How can ecosystem's change?
Removal or extinction of species, or just habitat destruction by an event (wildfire, human removal)
What is an example of an external factor causing a change in the diversity of an ecosystem?
An example of an external factor causing a change in the diversity of an ecosystem is deforestation. When forests are cleared for agriculture or urban development, it can lead to loss of habitat for many plant and animal species, resulting in a decrease in ecosystem diversity.
Every change that occurs in an ecosystem is harmful True or False?
False. Not every change that occurs in an ecosystem is harmful. Some changes can be beneficial, such as the introduction of a new species that fills a vacant ecological niche or the restoration of a degraded habitat. However, certain changes, such as habitat destruction or pollution, can have negative effects on the ecosystem.
What are two things mentioned in the reading that can happen that might affect an ecosystem?
Two factors that can significantly affect an ecosystem include climate change and habitat destruction. Climate change can alter temperature and precipitation patterns, impacting species survival and biodiversity. Habitat destruction, often due to urbanization or deforestation, can lead to loss of species and disruption of food chains, ultimately affecting the balance and health of the ecosystem.
How can a habitat change over time?
A habitat can change over time due to natural processes like climate change, succession, or geological events. Human activities such as deforestation, pollution, and habitat destruction can also significantly alter a habitat. These changes can impact the availability of resources, species composition, and overall ecosystem function.
What do you call ecosystems where species are endangered?
Endangered ecosystems are referred to as threatened ecosystems. This can happen when the balance between the different species within an ecosystem is disrupted, leading to a decline in the population of certain species. This imbalance can be caused by factors such as habitat destruction, pollution, climate change, and overexploitation.
What can cause this habitat to change?
Natural events such as wildfires, floods, hurricanes, or droughts can cause rapid changes in a habitat. Human activities like deforestation, pollution, urbanization, or climate change can also significantly alter habitats over time. Invasive species can outcompete native species and disrupt the balance of an ecosystem, leading to habitat changes.
How can overpopulation of a species be a problem to an ecosystem?
Overpopulation of a species can lead to competition for resources such as food and space, which can result in a decline of other species in the ecosystem. It can also lead to habitat destruction and increased pressure on the ecosystem overall, disrupting the balance of the ecosystem.
What happened to Australia's habitat and ecosystem?
Australia's habitat and ecosystem have faced significant challenges due to climate change, deforestation, and invasive species. These factors have led to habitat loss, degradation, and the decline of native species. Additionally, extreme weather events, such as bushfires and droughts, have intensified, further threatening biodiversity. Conservation efforts are underway, but the impacts on Australia's unique ecosystems continue to be a pressing concern.
How is the ecosystem likely to change as a result Select the two correct answers.?
Changes in temperature and weather patterns can shift habitats and impact species distribution. Human activities such as deforestation and pollution can disrupt ecosystem balance and lead to loss of biodiversity.
what is bad for ecosystem?
Factors that negatively impact ecosystems include pollution, habitat destruction, invasive species, and climate change. Pollution can contaminate air, water, and soil, harming wildlife and plant life. Habitat destruction, often due to urbanization and agriculture, reduces biodiversity and disrupts ecological balance. Invasive species can outcompete native species for resources, leading to declines in local populations and altering ecosystem dynamics.
How would the ecosystem's carrying capacity for a species change if the species cannot adapt to changes of habitat?
If a species cannot adapt to changes in its habitat, the ecosystem's carrying capacity for that species would likely decrease. This decline occurs because the species may struggle to find food, shelter, or reproduce effectively in altered conditions. As resources become limited or unsuitable, the population may decline, pushing it closer to extinction. Ultimately, the carrying capacity is determined by the species' ability to thrive within the available resources and environmental conditions.
