3. What is an ecosystem?An ecosystem is a group of living organisms that includes plants, animals, and microorganisms and interacts with its surroundings (soil, sun, precipitation).https://en.wikipedia.org/wiki

4. Ecosystem servicesThe numerous resources and processes that natural ecosystems supply benefit humans (Nuriyah et al. 2021). Collectively, these benefits such as food, and fresh water, as well as regulating services like climate regulation and pest control are known as ecosystem services (Nuriyah et al. 2021).https://19january2017snapshot.epa.gov/enviroatlas/ecosystem-services-enviroatlas

7. Bees in ecosystem services:Provisioning services Many products of bees, including honey, pollen, and propolis, have a long history of use in traditional medicine and food, while other products such as beeswax, bee venom, and royal jelly have more limited applications but still hold essential value in certain contexts. Here we discuss the three main products obtained from bees: honey, beeswax and propolis.https://en.wikipedia.org/wiki

8. Bees in ecosystem services:Provisioning services (continue) Honey is a well-known and widely consumed product of bees and it would not be wrong to say that honey product is the calling card of bees. Data obtained from http://www.fao.org/faostat

9. Bees in ecosystem services:Provisioning services (continue) Beeswax is a natural wax produced by bees that plays a crucial role in the life cycle of bees. Propolis is a resinous substance that is produced by bees by collecting plant materials and mixing them with their saliva and beeswax. Data obtained from http://www.fao.org/faostat

10. Bees in ecosystem services:Regulating services Bees play an important role in regulating ecosystem services, particularly in the pollination of plants that are important for soil conservation, climate regulation, and pest control. Pollination is a necessary procedure for transporting male gametes to female reproductive organs, which in turn increases crop yield (Aryal et al. 2020)STEP 1STEP 2STEP 3STEP 4

11. Bees in ecosystem services:Supporting services Bees contribute to the reproduction of flowering plants, the production of fruits, nuts, and seeds (Klein et al. 2007), and the maintenance of plant diversity and the productivity of ecosystems (Hoehn et al. 2008). These activities help to support carbon sequestration, soil health, and water regulation.https://www.pollinator.org/poster-2020

12. Bees in ecosystem services:Cultural services Bees play a crucial role in providing cultural ecosystem services, which refers to the non-material benefits that people obtain from nature, such as spiritual enrichment, aesthetic appreciation, and recreational opportunities.https://www.savethebee.org/4-important-best-practices-for-any-beekeeper/https://ecobnb.com/blog/2019/06/honey-bee-holidays-slovenia/

13. Threats to bee populationsGlobal bee populations have been declining over recent decades due to factors such as habitat loss, intensive farming practices, changes in weather patterns, and excessive use of agrochemicals like pesticides (FAO 2019).TOXIC PESTICIDESFARMING METHODSURBAN DEVELOPMENTS

14. ConclusionEcosystem services are essential for enhancing human well-being, and bees play a significant role in providing such services. We need to increase attention to bees as they provide several ecosystem services simultaneously. Therefore, it is necessary to pay special attention to the development of bee conservation programs and the promotion of sustainable agricultural practices that support bee populations.
