When did the first colonial organisms appear on earth?
1.4 billion years ago
Scientists are concerned that the depletion of the ozone layer will result in a reduction of populations of marine algae such as diatoms and dinoflagellates. Recall the ecological role of these organi?
They are the first organisms in the aquatic food chain.
WHAT is the ecological importance?
To answer this question, we must first consider - What is the meaning of ecological balance? Ecological Balance is a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession. It can also be referred to as 'a stable balance in the numbers of each species in an ecosystem'. In simple words, it is what keeps nature in harmony. Whatever is taken from the environment must be given back to it. In fact, phenomena like global warming, acid rain and pollution happen because the element taken from the environment is used up without replenishing it. If the ecological balance is disturbed, there can be drastic consequences, some of which are already happening
Why is it important to have a variety of organisms in a community of interacting species?
Having a variety of organisms in a community is important for several reasons. First, it ensures the stability and resilience of the ecosystem, as different organisms play diverse ecological roles and provide various services like nutrient cycling and pollination. Second, a diverse community enhances ecosystem productivity as each species has unique adaptations and capabilities. Lastly, biodiversity also contributes to human well-being through provisioning of resources like food, medicine, and materials.
In what way is observation important in ecological inquiry?
Observation is generally the very first step in asking ecological questions. Observations may be the first step in designing experiments and models.
What organisms are thought to have been the first to appear on earth?
bacteria
In what Era did the first land dwelling organisms appear?
the paleozoic era
When did the first multicellular organism appear?
Multicellular organisms first appeared during the Vendian period.
When did the first colonial organisms appear on earth?
1.4 billion years ago
Did animal appear first or did plant appear first?
Scientists believe that animals evolved from single-celled organisms in the oceans around 600 million years ago, making them the first to appear. Plants, on the other hand, evolved from ancient algae and appeared on land around 450 million years ago.
What is the first step in asking ecological questions?
observation is often the first step in asking ecological questions
How would succession be affected if animals did not return to an area after life?
Ecological succession is the phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following disturbance or initial colonization of new habitat. Succession was among the first theories advanced in ecology and the study of succession remains at the core of ecological science

Which organisms have produced the oldest fossil evidence?
Cyanobacteria are the first to appear in the fossil record.
What does each type of ecological pyramid depict?
An ecological pyramid is simply a graphical representation of the relationship at each trophic level in a particular ecosystem. There are three types of ecological pyramids: of numbers, of energy, and of biomass. For example the pyramid of numbers is a representation of the number of organisms in each trophic level, with herbivores at the bottom as primary consumers, followed by first level carnivores and so on.
