Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
What are the 4 major causes of biodiversity loss?
CAUSES OF BIODIVERSITY LOSS
- Climate change.
- Destruction of habitats.
- Invasive alien species.
- Overexploitation of the natural environment.
What are the 4 main causes of natural ecosystem degradation?
Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3).
What are the factors that affect the ecosystems?
They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components.
What are the four main drivers of ecosystem change?
The most important direct drivers of change in ecosystems are habitat change (land use change and physical modification of rivers or water withdrawal from rivers), overexploitation, invasive alien species, pollution, and climate change.

What are the 6 major causes of biodiversity loss?
Below, we discuss six of the major threats to biodiversity: climate change, habitat loss and degradation, pollution, invasive species, over-exploitation and epidemics. Learn how serious these threats are in contributing to the loss of biodiversity in our planet.
What are 5 biotic factors in an ecosystem?
5 Answers. Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
What are the five major causes of environmental problems?

What is diversity and biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What is the relationship between biodiversity and sustainability in an ecosystem?
Evidence suggests that biodiversity is critical for ecosystem function and services on which humans depend, and is directly linked to the economic, social, and environmental components of sustainability. Because of this, the integration of research from each of these areas should and is becoming a priority.
What are 3 main direct drivers in ecosystems and why do they affect ecosystems?
Important direct drivers include climate change, land-use change, invasive species and agro-ecological changes. Collectively these factors influence the level of production and consumption of ecosystem services and the sustainability of production.
What are four things that can change an environment?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
What is ecosystem diversity?
Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species.
