What are trade-offs in ecology?
In biology, a trade-off exists when one trait cannot increase without a decrease in another (or vice versa). Trade-offs also occur when characteristics that enhance one aspect of performance necessarily decrease another type of performance.
Why do consumers make trade-offs?
[see marginal analysis] Consumers continuously practice marginalism and make trade-offs as they consider whether to buy one more unit or one unit less of a good or service in their efforts to obtain a mix of goods and services that afford them the greatest satisfaction for their available buying power.
What is trade-off in plants?
As plants are unable to escape from stressful conditions, they must adapt to the external environment and activate defense systems in order to survive. In most plants, the activation of defense systems results in the suspension of growth – this is commonly known as the growth-defense trade-off.
Who makes trade-offs in economics?
Governments also make trade-offs when they decide to spend their money on military needs instead of domestic ones, and vice versa. In most trade-offs, one of the rejected alternatives is more desirable than the rest. The most desirable alternative somebody gives up as a result of a decision is the opportunity cost.
Who makes a trade-off?
Alternatives that people give up when they choose one course of action over another. Who makes trade-offs? Why do decisions involve trade-offs? The most desirable alternative given up as the result of a decision.
What is a trade-off in Economics quizlet?
Trade-off. an exchange that occurs as a compromise. Opportunity cost. the most desirable alternative given up as the result of a decision.
What is trade-off in agriculture?
Trade-offs, by which we mean exchanges that occur as compromises, are ubiquitous when land is managed with multiple objectives. Thus, trade-offs occur within agricultural systems, between agricultural and broader environmental or socio-cultural objectives, across time and spatial scales, and between actors.
What hormones are involved in the trade-off process?
GROWTH-PROMOTING HORMONE SIGNALING Growth hormones implicated in growth–defense tradeoffs are auxin, BRs, GAs, and cytokinins.
What is hypersensitive response in plants?
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens. HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
What is a trade-off in economics quizlet?
Who makes trade-offs and why do all decisions involve trade-offs?
Every decision involves trade-offs because every choice you want results in picking it over something else. You can’t always get what you want, like having two things. You must pick only one over the other. Summarize the concept of opportunity cost.
Why are trade-offs important in community ecology?
Trade-offs in species performances of different ecological functions is one of the most common explanations for coexistence in communities. Despite the potential for species coexistence occurring at local or regional spatial scales, trade-offs are typically approached at a single scale.
What is the definition of trade-off in economics?
Definition of Trade-Offs in Economics. In economics, the term trade-off is often expressed as an opportunity cost, which is the most preferred possible alternative. A trade-off involves a sacrifice that must be made to get a certain product or experience. A person gives up the opportunity to buy ‘good B,’ because they want to buy ‘good A’ instead.
Which is an example of an evolutionary trade-off?
Examples of trade-offs include those between longevity and fecundity (high fecundity shortens life); growth rate and carrying capacity; and between r -selection and K -selection. From: evolutionary trade-off in A Dictionary of Ecology »
Why do trade-offs occur in the biological system?
Trade-offs can occur because of inherent constraints of the biological, ecological, and physical system (called “biophysical” hereafter). Conflicts may then arise as a result of divergent preferences held by different service users and other stakeholders (Martín-López et al. 2012).
