Are plants R or K strategists?

Are plants R or K strategists?

Even plants are capable of r- and K-selected reproductive strategies. Wind pollinated species produce much more pollin that insect pollinated ones, for example, because the pollin has to be carried at random by the wind to a receptive female flower….r- and K-selection.

What are examples of R strategists?

Examples of r-strategist species are dogs, cats, insects, and fish.

What species are r strategists?

Organisms whose life history is subject to r-selection are often referred to as r-strategists or r-selected. Organisms that exhibit r-selected traits can range from bacteria and diatoms, to insects and grasses, to various semelparous cephalopods and small mammals, particularly rodents.

What is the meaning of r-selected species?

R-Selected Species – Definition. The r-selected species (or r-strategist) definition describes them as organisms that exhibit high reproductive rates followed by high mortality rates that lead to populations with highly fluctuating numbers.

What is a R strategist?

r strategist is an organism living in unstable environments. Hence, they undergo rapid reproduction to stabilize themselves. Whereas, K strategist is an organism living in stable environments. Therefore, they are high in population and do not need to undergo rapid reproduction.

Which of the following is the best example of an r-selected species?

The R in R-selected represents population growth rate. Dandelions are particularly good examples of R-selected traits because they have several of the physical characteristics associated with R-selected traits including: rapid development, small size, and short lifespan.

Are dandelions r-selected?

(b) Dandelions and jellyfish are both considered r-selected species as they mature early, have short lifespans, and produce many offspring that receive no parental care.

Which of the following is a trait of R strategist organisms?

So, the correct answer is ‘Large offspring’.

What is R strategist?

What are the features of r-selected species?

These characteristics describe R-selected species perfectly:

• Rapid development.
• High reproductive rate.
• Early reproductive age.
• Small body size.
• One reproductive cycle.
• Short lifespan.
• Poor competitive ability.
• High mortality of offspring.

What’s the difference between R strategist and K strategist?

The key difference between r strategist and K strategist is that the r strategist lives in unstable and unpredictable environments while the K strategist lives in more stable environment. Because of this environmental conditions, the r strategists produce many offspring while the K strategists produce few offsprings.

Is a sea turtle r-selected?

r/K selection as a continuous spectrum Similarly, reptiles such as sea turtles display both r- and K-traits: although large organisms with long lifespans (should they reach adulthood), they produce large numbers of unnurtured offspring.

Are pioneer species R or K-selected?

Answer and Explanation: Pioneer species are most commonly R-selected species. This means that they have shorter lifespans, tend to be smaller plants, and usually produce multiple offspring.

What traits do r-selected species have in common?

What does R strategist and K strategist mean?

Are rabbits r-selected?

R-selected organisms, those emphasizing a fast growth rate, high number of offspring, include rabbits, bacteria, salmon, plants such as weeds and grasses, etc.

Are dandelions r-selected species?

Examples of r-selected species are marine invertebrates, such as jellyfish, and plants, such as the dandelion. Dandelions have small seeds that are dispersed long distances by wind; many seeds are produced simultaneously to ensure that at least some of them reach a hospitable environment.

What is AK strategist species?

K-selected species, also called K-strategist, species whose populations fluctuate at or near the carrying capacity (K) of the environment in which they reside. Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O.

What are some examples of r strategists and K strategists?

Bacteria, insects and corals are few examples of r strategists while human, primates, and elephants are few examples of K strategists. One other notable difference between r strategist and K strategist is their sizes.

What are the characteristics of K strategist species?

Characteristics of k-strategists. K strategist species show similar characteristics of reproduction like: Occasional breeding; Longer gestation periods and give birth to one or two offspring at a time; Offspring take time to grow, and do so under the constant care and supervision of their parents.

What is an example of a K-strategist species?

Common examples of k-strategists species include humans, lions and whales. R-strategists “live” near the line of exponential growth r. These organisms are nowhere near the carrying capacity, and can therefore afford to grow their population.

What is an r-strategist?

R-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r ). Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O.
