Ecology Flashcards
It is the study of interactions among living things and their environment.
Ecology
It shows the individuals the extent of damage we cause to the environment.
Conservation of Environment
With the knowledge of ecology, we can know which resources are necessary for the survival of different organisms.
Resource allocation
Proper knowledge of ecological requirements prevents the unnecessary wastage of energy resources, thereby, conserving energy for future purposes.
Energy Conservation
Ecology encourages harmonious living withing the species and the adoption of a lifestyle that protects the ecology of life.
Eco-friendliness
Types of Ecology of Life
✓ Global Ecology
✓ Landscape Ecology
✓ Ecosystem Ecology
✓ Community Ecology
✓ Population Ecology
✓ Organismal Ecology
✓ Molecular Ecology
TYPES OF ECOLOGY OF LIFE
It deals with interactions among earth’s ecosystem, land, atmosphere, and oceans.
Global Ecology
TYPES OF ECOLOGY OF LIFE
It deals with the exchange of energy, materials, organisms, and other product of ecosystem.
Landscape Ecology
TYPES OF ECOLOGY OF LIFE
It deals with the entire ecosystem, including the study of living and non-living components and their relationship with the environment.
Ecosystem Ecology
TYPES OF ECOLOGY OF LIFE
It deals with how community structure is modified by interactions among living organisms.
Community Ecology
TYPES OF ECOLOGY OF LIFE
It deals with factors that alter and impact the genetic composition and the size of the population of organisms.
Population Ecology
TYPES OF ECOLOGY OF LIFE
Is the study of an individual organisms’ behaviour, morphology, physiology, etc., in response to environmental challenges.
Organismal Ecology
TYPES OF ECOLOGY OF LIFE
It is the study of ecology that focuses on the production of proteins and how these proteins affect the organisms and their environment.
Molecular Ecology
Levels of Organization in Ecology
• Biosphere
• Ecosystem
• Community
• Population
• Organism
LEVELS OF ORGANIZATION IN ECOLOGY
The highest level of organization. It consists of all the living organisms and other factors which support life.
Biosphere
LEVELS OF ORGANIZATION IN ECOLOGY
Is a community of LIVING AND NON-LIVING things interacting in a specific area or habitat.
Ecosystem
LEVELS OF ORGANIZATION IN ECOLOGY
Refers to a group of DIFFERENT SPECIES living and interacting in a specific area or ecosystem.
Community
LEVELS OF ORGANIZATION IN ECOLOGY
Refers to a group of individuals of the SAME SPECIES living in a specific area.
Population
LEVELS OF ORGANIZATION IN ECOLOGY
Is an individual living being, such as plant, animal, or microbe. Lowest level of hierarchical organization.
Organism
Theory that describes the arrangements of biological organisms in relation to one another.
Ecological Theory
It means anything that surrounds us.
Environment
What is biotic?
Living things
What is abiotic?
Non-living things
Two Types of Environment
• Geographical Environment
• Man-made Environment
It is the terrestrial environment that is a creation of complex natural and environmental conditions.
Geographical Environment
It is also called a social environment.
Man-made environment
Two Types of Man-made Environment
• Inner Environment
• Outer Environment
It is a social environment that endures as long as society cherishes. It is often called “social heritage”.
Inner Environment
It is the physical environment that man has created on his own with the evolving technology and science.
Outer Environment
Is an ecological concept that describes how ecosystems exist in a DYNAMIC state of balance or equilibrium.
Ecological Balance or Ecological Equilibrium
It means that despite disturbances, which may be natural or anthropogenic, a balanced ecosystem remains stable.
Dynamic Equilibrium
Without ______, life could not exist.
Carbon
____ ___ are balanced systems of energy transfer that keep the populations of animals, plants, and microorganisms within an ecosystem in check.
Food Webs
Examples of Natural Disturbances
✓ Volcanic Explosion
✓ Flood
✓ Forest Fire
✓ Overgrowth of species
Examples of Man-Made Disturbances
✓ The birth of a new specie
✓ Exploiting forests
✓ Pollution
✓ Deforestation
✓ Invasive Species
It refers to a place that is extremely rich in flora and fauna
Biodiversity Hotspots
The gradual thinning of ozone layer
Ozone depletion
It means the increasing temperature of the earth’s atmosphere.
Global Warming
Any form of precipitation with acidic components.
Acid rain
It is the change of thermal effect of the planet.
Greenhouse Effect
3 Classifications of Environment
• Physical
• Biological
• Cultural
Atmosphere, hydrosphere, lithosphere, abiotic and natural environment - non-living (land, water, air) belongs to ________ Classification of Environment.
Physical
(Biotic and organic) living things, flora (plant life), fauna (animal life), and microscopic organisms belong to the ___________ Classification of Environment.
Biological
Society, economy, and politics - created by man with the different responsibilities belong to the ________ Classification of Environment.
Cultural
It refers to the migration of population from high-density urban areas to low-density rural areas.
Urban sprawl
Refers to the pollution problems.
Single Medium Problems
Means one of the problem is confined to soil, air, or water.
Multi-Medium Problem
It is the rapid increase of population.
Economic boom
