Chapter 19: Problem 20

What is meant by ecosystem stability?

Short Answer

Expert verified

Ecosystem stability refers to the ability of an ecosystem to withstand alterations or recover to its original state after disturbances while maintaining its biodiversity and production.

Step by step solution

Define Ecosystem

The first step is to understand the term 'ecosystem'. An ecosystem is a specific area where living organisms interact among themselves and with the surrounding environments including factors such as air, water and soil. This concept involves interdependence between different elements in a certain environment.

Understand the Concept of Stability

In the context of an ecosystem, stability refers to the ability of an ecosystem to maintain its features and functions over time despite disturbances. Ecosystem disturbances could be natural like hurricanes, floods, fires, or caused by human activities such as deforestation and pollution.

Combine the Definitions

By combining definitions of both ecosystem and stability, it can be concluded that ecosystem stability refers to the ability of an ecosystem to withstand changes or recover to its original state after being disturbed, maintaining its biodiversity and production.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Ecosystem

Imagine an ecosystem as a bustling city where each resident has a specific role, and the neighborhood's well-being depends on everyone working harmoniously. In simpler terms, an ecosystem consists of all the living creatures in a particular area, mingling with each other and their physical surroundings, like air, water, and soil.

Think of a forest, with its trees, animals, birds, insects, and the underlying soil and weather conditions - they all form an interconnected web that's the forest ecosystem. These interactions are crucial, as they impact survival and can adjust to gradual changes over time to maintain a balanced 'neighborhood'.

Environmental Disturbances

Environmental disturbances are like unexpected events that shake up the regular life in our metaphorical city, the ecosystem. They come in various forms, ranging from natural disasters, like earthquakes and floods, to human-induced changes such as deforestation and pollution.

These disturbances can cause immediate and sometimes long-term effects on an ecosystem's structure and function. For instance, a hurricane can knock down trees, which in turn affects the birds that nest in them and the animals that rely on the forest cover. Understanding these disturbances is essential to gauge an ecosystem's resilience and capacity to bounce back to its former state.

Biodiversity

Biodiversity is the array of different forms of life - from the tiniest microorganisms to the largest mammals - and the varied ecosystems they inhabit. It's like having a wide variety of jobs and skills within our ecosystem 'city'. High biodiversity usually means an ecosystem has a rich variety of plants and animals, which contributes to its overall health and stability.

More diverse ecosystems are often more resilient, bouncing back more readily from disturbances. They can be thought of as a team with many different players; if one player is taken out, there are others to fill in, ensuring the team continues to function.

Ecological Interdependence

Ecological interdependence is the mutual reliance between different organisms within an ecosystem. Every species, from the smallest insect to the top predator, is an essential piece of the ecosystem puzzle. Plants, for example, provide oxygen and food, which are crucial for animals. In turn, animals can pollinate plants and redistribute their seeds.

In our ecosystem 'city', this is like the various public services and citizens depending on each other. If the waste disposal team fails, the city becomes unclean, leading to diseased residents and a dysfunctional city. Similarly, if bees, which are key pollinators, become scarce, plants might not reproduce effectively, leading to repercussions up the food chain.
