Competition and Interdependence in Ecosystems
This section of the Detailed ecology mind map for students pdf focuses on the fundamental concepts of competition and interdependence within ecological communities. It explains how species rely on each other and compete for resources, highlighting the delicate balance in ecosystems.
Definition: Interdependence refers to the mutual reliance of species on each other within an ecosystem.
The mind map outlines the main areas of competition for both plants and animals:
- Plants compete for space, food (mineral ions), and light.
- Animals compete for space, food, and mates.
Highlight: Any change in an ecosystem can have significant effects due to the interconnectedness of species.
The section also introduces abiotic and biotic factors, which are crucial components of any ecosystem:
- Biotic factors include competition, new predators, food availability, and new pathogens.
- Abiotic factors encompass light intensity, temperature, CO₂ levels, and moisture levels.
Vocabulary: Abiotic factors are non-living components of an ecosystem, while biotic factors are living components.
The mind map then delves into adaptations, explaining that they allow organisms to survive in their environments. It categorizes adaptations into three types:
- Structural
- Behavioral
- Functional
Example: Microorganisms have a wide variety of adaptations, enabling them to thrive in diverse environments.
This comprehensive overview provides students with a solid foundation for understanding ecological relationships and serves as an excellent resource for Biology paper 2 mind map preparation.
