Carrying Capacity & Biodiversity
factors are the living components of an ecosystem that affect the carrying capacity. These include predators, competitors, prey, and symbiotic relationships.
Biotic Factors
An ecosystem's ability to maintain a relatively constant state, with consistent numbers and types of organisms, despite minor disturbances
Ecosystem Stability
non-native organisms that, when introduced to a new environment, can outcompete native species for resources, leading to a decrease in biodiversity. Human activities such as global trade and travel facilitate the spread of invasive species.
Invasive Species
The following are all examples of ____________
Industrialization, water pollution, toxic wastes, thermal pollution, heat Pollution, human overpopulation, air pollution, and burning fossil fuels
Impact of Technology and Industrialization
Cooperative hunting or foraging can lead to more effective food acquisition. Wolves hunt in packs to take down prey that would be too difficult to catch alone. This is an example of what type of group behavior?
Efficient Resource Use
the maximum number of individuals of a species that an ecosystem can support over time without depleting resources.
Carrying Capacity
break down dead, decaying organisms and return nutrients to the soil. They are the recyclers in the ecosystem and are at the end of every food chain, food web, and food pyramid.
Decomposers
The growth of cities and infrastructure often leads to the destruction of natural habitats, fragmentation of ecosystems, and increased pollution. This can result in a decline in species diversity and the disruption of natural processes.
urbanization
Sulfur and nitrogen compounds in air pollution dissolve in the moisture of the atmosphere toform acids, causing rain to have a low pH (acidic).
Acid Rain
_______________ involves actions taken collectively by multiple individuals to achieve common goals, such as safety or resource acquisition while _____________ involves a single organism to fulfill its needs, often without direct coordination with others.
group behavior and individual behavior
Examples include Food, Shelter, Sun, Space, Oxygen,
Limiting Factors
The following are all aspects of a _____________
1. a constant source of energy
2. a process to capture the energy and store it in organic molecules.
3. a way to recycle elements back to the ecosystem.
Self Sustaining Ecosystem
The development of technological innovations, the creation of legislation and policies, and the implementation of conservation practices are all examples of _________________
Solutions to Environmental Challenges
__________ is an increase in the earth’s temperature caused by an increase in greenhouse gases (GREENHOUSE EFFECT is caused by increasing amounts of CO2 in the atmosphere caused by the increasing use of fossil fuels for energy). It can lead to ______________ which causes a huge reduction in coral reefs
Global warming, and coral bleaching
Many animals use group behaviors to increase their chances of evading predators. For instance, schools of fish can create confusion among predators through their coordinated movements. This is an example of what type of group behavior?
Protection from Predators
Two bird species might live in the same tree but feed on different insects at different times is an example of ____________
Niche
Identify the following symbiotic relationships in order
1. a relationship where one organism benefits and the other is not affected
2. a relationship where one organism benefits and the other is harmed.
3. a relationship where both organisms benefit
1. Commensalism
2. Parasitism
3. Mutualism
The destruction or loss of a species by over hunting, destroying a part of the natural environment, removing forests for wood or clearing trees for farms, and introducing invasive species are all examples of ______________ that leads to ______________
Human activities, a loss of biodiversity
Ozone depletion is hole in ozone layer caused by use of fluorocarbons. Ozone depletion can result in an increased risk in ____________
Skin cancer
Animals that migrate in groups can find better breeding grounds and ensure higher survival rates for their offspring. This is an example of what type of group behavior?
Improved Reproduction
Fewer species = fewer niches filled, more competition, ecosystem becomes less stable, invasive species may move in, and less genetic diversity are all a result of ________________
loss of biodiversity
the process by which ecosystems change over time, particularly after a disturbance. Succession can be primary, starting from bare rock or soil, or secondary, where an existing ecosystem is altered but not completely destroyed.
Ecological Succession
Identify the different ways in which we can preserve our resources
1. can be used to make the product again (like pop bottles)
2. cut down on the amount used (smaller packaging)
3. use it for another application (old tires as flower planters)
1. recycle
2. reduce
3. reuse
An increase in global warming and carbon dioxide levels in the ocean can result in _____________ which negatively affects marine organisms by inhibiting their ability to build ______________
ocean acidification, shells
Flocking, schooling, herding, cooperative hunting, and migration are examples of ____________
Evidence Supporting Group Behavior
