Which of the following describes how an abiotic factor can impact the population dynamics in an ecosystem?
A. A parasite that invades a host can reproduce and cause a decline in the host species population.
B. Organisms that compete for the same resources will keep each other from overpopulating.
C. Predators will prevent herbivores from depleting the plants and other resources in an ecosystem.
D. Seasonal variations in temperature can cause some of the individuals in a population to die.
How is primary succession different from secondary succession?
Primary succession starts with soil.
Secondary succession start with bare rock.
Primary succession starts with bare rock, with lichens and moss.
Fire is an example of primary succession.
Examples of Abiotic Factors include:
Weather, birds, plants, and animals
Rocks, reptiles, shrubs, trees, and grasses
Weather, wind, rain, sunlight, and rocks
Birds, plants, animals, reptiles, shrubs, trees, and grasses
Several years after a building had been torn down and the ground cleared, grasses began to grow in that area. After 10 years, small bushes replaced the grasses. This pattern of plant growth is known as:
Biological
control
Cover cropping
Ecological
succession
Land-use
management
A volcano in a mountainous, wooded region erupts, spewing tons of ash and destroying the forested area around the volcano. If the volcano remains dormant during
the next 1000 years, what will probably happen?
The area will be repopulated by trees, eventually becoming a
forest again.
The mountains will erode and remain without life.
The area will remain unchanged, covered by volcanic ash.
The area will turn into a completely different habitat, such as
desert of plains.
How has the invasion of pythons effected the everglades ecosystem in terms of species numbers?
The pythons could upset the territorial boundaries of native organisms.
The pythons could adapt to overcome diseases common to native snakes.
The pythons could prey on native organisms and cause native populations to decline.
The pythons could begin to interbreed with native snakes and produce a more successful species.
Scientists found, that over a period of 200 years, a mountain pond was transformed into a meadow. During that time, several communities of organisms were replaced by different communities. Which of these best explains why new communities were able to replace older communities?
A.The original species became extinct.
A.Species in the older community died from old age.
A.The abiotic characteristics of the habitat changed.
