Which of these interaction describes this scenario cattle egrets and livestock as they graze cattle stir up insects which are eaten by the cattle egrets?
As cattle graze on the field they stir up insects from the ground. As this happens Cattle Egrets follow the livestock and eat the insects. Which kind of symbiosis is this? This is commensalism because only the Cattle Egrets are benefitting from the relationship.
Which of the following is an example of a Commensalism cattle egrets?
Which of the following is an example of commensalism? Cattle egrets walk beside cattle, eating insects disturbed by the movements of the cows. What does it mean to say that a species has a wide niche breadth?
When water buffalo graze they stir up insects which can then be eaten by egrets birds the interaction between the water buffalo and the egret is an example of?
commensalism
What does it mean to say that a species has a wide niche breadth BIO 180?
What does it mean to say that a species has a wide niche breadth? It can use a wide array of values of a particular resource or tolerate an array of conditions.
Which of the following is an example of Commensalism BIO 180?
Which of the following is an example of commensalism? Cattle egrets walk beside cattle, eating insects disturbed by the movements of the cows. What does it mean to say that a species has a wide niche breadth? It can use a wide array of values of a particular resource or tolerate an array of conditions.
What is the most important difference between species richness and species diversity quizlet?
What is the most important difference between species richness and species diversity? Species diversity takes species number AND relative frequency into account.
What is species richness group of answer choices?
Species richness is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions.
What are researchers referring to when they talk about primary secondary tertiary consumers or Detritivores quizlet?
What are researchers referring to when they talk about “primary, secondary, tertiary” consumers or detritivores? Trophic level, meaning position in a food chain (e.g. secondary eat primary). What do detritivores eat?
What’s the difference between species richness and index of diversity?
Explanation: Species richness is the number of species found in a community or ecosystem. Species diversity is a measurement of species richness combined with evenness, meaning it takes into account not only how many species are present but also how evenly distributed the numbers of each species are.
Which is a better index of diversity low or high?
Richness is a measure of the number of different kinds of organisms present in a particular area. For example, species richness is the number of different species present. However, diversity depends not only on richness, but also on evenness….
| Species | Number (n) | n(n-1) |
|---|---|---|
| Total (N) | 15 | 64 |
What are the three key factors that influence species richness in an ecosystem?
Many factors affect small‐scale species richness, including geographic (e.g. species pool, dispersal), biotic (e.g. competition, predation, facilitation) and abiotic (e.g. resource availability, environmental heterogeneity, disturbance frequency and intensity).
How does species richness affect an ecosystem?
Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
What are the 5 main threats to biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
Why is species richness important for an ecosystem?
Number of species per unit area is called Species Richness. If you have more number of species , more will be species richness hence stable will be the ecosystem. More species richness will contribute to increase in biodiversity also which is an important aspect biodiversity conservation.
How important is an individual species to an ecosystem?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What is the role of species in an ecosystem?
Key Concept Each species plays a specific ecological role called its niche. Key Concept Any given species may play one or more of 5 important roles – native, nonnative, indicator, keystone, or foundation – in a particular ecosystem.
What keeps an ecosystem stable?
The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem’s ability to remain stable when confronted with a disturbance. First is to maintain a diversity of plants and animals in an ecosystem. Humans have a tendency to simplify ecosystems to maximize one particular output.
Why is it important that a community is stable?
The stability-diversity hypothesis states that the more diverse a community is, the more stable and productive the community is. This hypothesis was formed from the basis that more stable and productive communities can use their resources better and more efficiently as compared to communities of less diversity.
