2.3 Effects on terrestrial vegetation
Managing eutrophication is a key element in maintaining the earth's biodiversity. Eutrophication is a process mostly associated with human activity whereby ecosystems accumulate minerals. This unit explains how this process occurs, what its effects on different types of habitat are, and how it might be managed.

Introduction

This Unit is designed to provide you with a basic framework for understanding operations management and its organisational and managerial context. It begins with a brief history of the changing nature of operations in a manufacturing context, but emphasises that the operations function is significant in all types of organisation, whether they produce goods or provide services, and whether they are in the private, public or voluntary sectors.

This Unit presents a process model of operati

4.6 Hormonal control of egg production
This unit looks at the human being in the context of an individual life cycle, examining some of the processes that contribute to the formation of a new person. After a brief discussion of historical ideas about human conception, and about contraception to the present day, we look at the cells involved in the conception and development of a new individual. Gamete production (that is, production of mature cells able to unite with another in sexual reproduction) in both men and women is introduced
