Symbiotic Relationships
What is symbiosis?
A close, long-term relationship between two different species.
What are the 6 steps of natural selection in order
1. Variation
2. Overproduction
3. Differential Survival and Reproduction
4. Heredity
5. Accumulation of Favorable Traits
6. Adaptation
This type of resource exists in finite quantities and cannot be replenished within a human timescale
Non Renewable
What is poverty?
A state of being extremely poor.
What is population growth?
The increase in the number of people in a given area
What is mutualism?
Both species benefit. (e.g., clownfish and sea anemone)
What is the meaning of natural selection
Natural selection is how species change over time. Individuals with helpful traits are more likely to survive and reproduce, passing those traits to their offspring. This process leads to the evolution of new species and the diversity of life.
List 3 types of renewable resources
Sunlight, Water, Wind
How can education help reduce poverty?
Increased job opportunities, higher earning potential, improved health outcomes, better decision-making skills, etc.
List 4 factors that affect population growth
Immigration, Emigration, Death and Birth Rate
What is commensalism?
One species benefits, the other is unaffected. (e.g., barnacles and whales)
Discuss the concept of heritability in natural selection
Heritability is the ability of traits to be passed from parents to their children. It's key for natural selection, as it allows helpful traits to be passed on, making future generations better adapted.
List 3 non renewable resources
Coal, Oil, Natural Gases, Minerals and Earth metals
What is the relationship between poverty and healthcare access?
limited access to healthcare, poorer health outcomes, higher rates of chronic diseases, etc.
What is carrying capacity?
Overpopulation, reached maximum, limited resources.
What's an example of plant-animal mutualism?
Bees and flowers: bees get nectar, flowers get pollinated.
Explain the significance of genetic variation in the context of natural selection
Genetic variation is the difference in genes between individuals. It's like the raw materials for natural selection. Without it, there would be no traits for natural selection to choose from, and species couldn't adapt.
This type of energy is derived from the heat stored beneath Earth's surface and is used to generate electricity or provide direct heating.
Geothermal Energy
Discuss the impact of cultural biases and stereotypes on poverty reduction efforts.
stigmatization, discrimination, limited access to resources, etc.
Difference between rural and urban areas
Rural areas are less populated, with open land and agriculture, while urban areas are densely populated with buildings and industries.
How does symbiosis affect ecosystems?
It can increase or decrease diversity. Mutualism can lead to co-evolution, while parasitism can harm or kill hosts.
Explain the 6 steps of natural selection
Explain how natural resources are essential for human survival
Natural resources like water, air, food, and minerals are essential for human survival as they provide the basic necessities for life and support various human activities.
How does poverty contribute to environmental degradation?
Reliance on natural resources for survival, lack of access to clean energy, poor waste management practices, etc.
What is the difference between population growth and population density?
Population growth is the increase in the number of individuals in a population over time. Population density is the number of individuals in a population per unit of area.
