Study Notes
Key Strategies in Plant Competition
- Plants compete for resources such as light, water, and nutrients to survive and thrive.
- Adaptations like growing taller or developing deeper root systems are common strategies in this competition.
Purpose of Evidence in the CER Framework
- In the Claim-Evidence-Reasoning (CER) framework, evidence supports claims and provides factual backing.
- It enhances the credibility of arguments and ensures conclusions are based on observable data.
Resource Competition Among Organisms
- When organisms utilize the same resources, competition can lead to resource depletion.
- This competition can result in one species dominating over others or can lead to adaptation changes in the competing organisms.
Constraints in Decision-Making
- Constraints are limitations that influence the choices available during decision-making processes.
- They can include factors such as time, resources, regulations, or environmental conditions.
Impact of Food Source Decline on Species Population
- If a primary food source declines, the population of the dependent species is likely to decrease.
- This can lead to starvation, reduced reproductive rates, or migration to find alternative food sources.
Mutual Relationships in Ecology
- Mutualism is the type of relationship characterized by benefits to both organisms involved.
- Examples include pollinators and flowering plants where both gain from the interaction.
Consequences of Decline in Apex Predator Population
- A significant decline in apex predator populations can lead to an overpopulation of prey species.
- This imbalance can disrupt the ecosystem, causing potential overgrazing and loss of vegetation.
Characteristics of Invasive Species
- Invasive species often have rapid multiplication rates and lack natural predators in new environments.
- They can outcompete native species for resources, leading to biodiversity loss.
Impact on Treecreeper if Caterpillar Populations Decline
- If caterpillars, a food source for Treecreepers, suddenly disappear, it can lead to decreased Treecreeper populations.
- The Treecreeper may suffer from starvation or reduced reproductive success.
Direction of Arrows in Food Chain Diagrams
- Arrows in food chain diagrams point towards the organism that receives energy; they indicate the direction of energy transfer.
- This illustrates predator-prey relationships and energy flow in ecosystems.
Impact of Small Changes in Ecosystems
- Small changes in ecosystems can have significant ripple effects, altering species interactions and ecosystem stability.
- This phenomenon illustrates the delicate balance of ecological relationships and the potential for cascading impacts.
