SENIOR SECONDARY SCHOOL (SSS 1)
THEME: AGRICULTURE ECOLOGY
TOPIC – AGRICULTURAL ECOLOGY AND ECOSYSTEM
1. Agricultural Ecology and Ecosystem
2. Components of Farm Ecosystem
3. Animals Interact with other Organisms and Non Living Things under different Farm Settings
By the end of the lesson, most of the students should have attained the following objectives –
1. Define agricultural ecology and ecosystem.
2. State four (4) components of farm ecosystem.
3. Discuss how farm crops/animals interact with other organisms and non living things under different farm settings.
The teacher will teach the lesson with the aid of natural farm settings, ponds, forest set up.
METHOD OF TEACHING
Choose a suitable and appropriate methods for the lessons.
Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.
1. Scheme of Work
2. National Curriculum for SSS Classes
3. Course Book
4. All Relevant Material
5. Online Information
CONTENT OF THE LESSON
MEANING OF AGRICULTURAL ECOLOGY
Agricultural ecology is the study of agricultural ecosystems and their components as they function within themselves and in the context of the landscapes that contain them.
MEANING OF ECOSYSTEM
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.
COMPONENTS OF FARM ECOSYSTEM
Biotic parts include plants, animals, and other organisms.
Abiotic parts are non living things. Non living components include air, water, land.
Autotrophism is the ability to produce organic matter by reducing inorganic matter using an external energy source – light (photoautotrophism) or chemical reactions (chemoautotrophism).
Heterotrophism is the ability to produce organic material only from organic carbon sources obtained from animal or plant biosynthesis. This property is a feature of mycetes (fungi) and animals.
The concept of heterotrophism is the opposite of that of autotrophism.
IMPORTANCE OF AGRICULTURAL ECOLOGY
1. It increases the crops production.
2. It controls soil erosion.
3. It protects crops pests and insects.
4. It conserves soil fertility.
INTERACTIONS OF THE COMPONENTS IN THE TERRESTRIAL AND AQUATIC AGRO – ECOSYSTEM
1. Mono or sole cropping system.
2. Mixed cropping system.
3. Mixed farming system.
4. Fish ponds.
5. Forest (rain forest o r savanna).
To deliver the lesson, the teacher adopts the following steps:
1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the students some questions; then, the teacher –
2. Takes students out to a natural farm setting.
3. Explains the key concepts.
4. Guides discussions on the relationships between organisms of interest (plant/animals and other organisms or non-organisms).
Student’s Activities – Listen and interact with the environment.
5. Groups students for out of class study of different farm settings.
Student’s Activities – Undertake group work and produce reports.
6. Summarizes the lesson on the board.
Student’s Activities – Copy as the teacher writes.
To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
Ask students to:
1. State the meaning of agricultural ecology and ecosystem.
2. What are the components of a farm ecosystem.
3. Identify at least three farm settings and discuss how farm crops/animals interact with other components of the ecosystem.
