STAGE 1 BIOLOGY SEMESTER 1 TOPIC 4

TERM 2: Topic 4: BIODIVERSITY AND ECOSYSTEM DYNAMICS

The current view of the biosphere is of a dynamic system composed of Earth’s diverse, interrelated, and interacting ecosystems. This concept, developed from the work of naturalists who collected, classified, measured, and mapped the distribution of organisms and environments around the world, forms the basis of strategies, protocols, and government policy for the protection of ecosystems. This topic investigates diverse ecosystems, exploring the range of biotic and abiotic components to understand the dynamics, diversity, and underlying unity of these systems. Investigating ecosystem dynamics, including interactions within and between species, and interactions between abiotic and biotic components of ecosystems helps develop an understanding of the processes involved in the movement of energy and matter in ecosystems. Measurements of abiotic factors, population numbers and species diversity, and descriptions of species interactions, provides the basis of meaningful comparisons between ecosystems. Classification keys are used to identify organisms, describe the biodiversity in ecosystems, and investigate patterns and changes in relationships between species. Numeracy is enhanced through practical activities and possible fieldwork which involves individual and/or collaborative collection of first-hand data. Literacy is extended through analysing and interpreting data collected through investigation of a local environment, and from sources related to other local, regional, and/or global environments.

Science Understanding Learning Activities Resources

Week 1 Monday (Single)

Biodiversity is the variety of all living things and includes diversity in genetics, species, and ecosystems. • Describe diversity in examples of: species ecosystems.

In general, the higher the biodiversity of an ecosystem, the more stable it is.

Week 1 Thursday (Double Lesson)

Biological classification is hierarchical and indicates the relationship between organisms based on their physical structures and the similarities in shared molecular sequences.

There is an internationally agreed system of nomenclature of species which undergoes revision. • Distinguish between scientific names and common

names for species. • Recognize that very closely related species have

similar scientific names. Discuss the advantages of an internationally agreed system of nomenclature.

Ecosystems can be diverse, and can be defined by their biotic and abiotic components and the interactions between elements of these components. • Distinguish between biotic and abiotic components

of ecosystems. Inter- and intraspecific interactions such as

symbiosis, competition, predation, and disease. Interactions between biotic components of ecosystem:

Ecosystems include populations of organisms that each fills a specific ecological niche. • Describe a niche in terms of key indicators within

the ecosystem, including habitat, feeding relationships, and interactions with other species.

Keystone species play a critical role in the maintenance of their ecosystem. • Explain the significance of keystone species in

their ecosystem.

Humans have significant impacts on ecosystems. • Explain how the destruction of habitats as a result

of human activity speeds up changes in ecosystems and impacts on biodiversity.

By measuring key aspects of the biotic and abiotic components of the ecosystem, it is possible to make predictions relating to the impact of environmental change. Describe how these predictions can help to develop

strategies to minimise the adverse effects of such change.
